SYNOPSIS
Instance_map::flush_instances()
DESCRIPTION
This function will:
- clear the current list of instances. This removes both
running and stopped instances.
- load a new instance configuration from the file.
- pass on the new map to the guardian thread: it will start
all instances that are marked `guarded' and not yet started.
Note, as the check whether an instance is started is currently
very simple (returns TRUE if there is a MySQL server running
at the given port), this function has some peculiar
side-effects:
* if the port number of a running instance was changed, the
old instance is forgotten, even if it was running. The new
instance will be started at the new port.
* if the configuration was changed in a way that two
instances swapped their port numbers, the guardian thread
will not notice that and simply report that both instances
are configured successfully and running.
In order to avoid such side effects one should never call
FLUSH INSTANCES without prior stop of all running instances.
NOTE: The operation should be invoked with the following locks acquired:
- Guardian;
- Instance_map;
/**
Check if there is an active instance or not.
*/
int Instance_map::flush_instances()

All objects created in the Manager object live as long as thread_registry

There are two main purposes of the Thread Registry:
1. Interrupt blocking I/O and signal condition variables in case of
shutdown;
2. Wait for detached threads before shutting down the main thread.
NOTE:
1. Handling shutdown can be done in more elegant manner by introducing
Event (or Condition) object with support of logical operations.
2. Using Thread Registry to wait for detached threads is definitely not
the best way, because when Thread Registry unregisters an thread, the
thread is still alive. Accurate way to wait for threads to stop is
not using detached threads and join all threads before shutdown.

/**
Re-read instance configuration file.
SYNOPSIS
flush_instances()
DESCRIPTION
This function will:
- clear the current list of instances. This removes both
running and stopped instances.
- load a new instance configuration from the file.
- pass on the new map to the guardian thread: it will start
all instances that are marked `guarded' and not yet started.
Note, as the check whether an instance is started is currently
very simple (returns TRUE if there is a MySQL server running
at the given port), this function has some peculiar
side-effects:
* if the port number of a running instance was changed, the
old instance is forgotten, even if it was running. The new
instance will be started at the new port.
* if the configuration was changed in a way that two
instances swapped their port numbers, the guardian thread
will not notice that and simply report that both instances
are configured successfully and running.
In order to avoid such side effects one should never call
FLUSH INSTANCES without prior stop of all running instances.
