TABLE ... WRITE". Memory and CPU hogging occured when connection which had to wait for table lock was serviced by thread which previously serviced connection that was killed (note that connections can reuse threads if thread cache is enabled). One possible scenario which exposed this problem was when thread which provided binlog dump to replication slave was implicitly/automatically killed when the same slave reconnected and started pulling data through different thread/connection. The problem also occured when one killed particular query in connection (using KILL QUERY) and later this connection had to wait for some table lock. This problem was caused by the fact that thread-specific mysys_var::abort variable, which indicates that waiting operations on mysys layer should be aborted (this includes waiting for table locks), was set by kill operation but was never reset back. So this value was "inherited" by the following statements or even other connections (which reused the same physical thread). Such discrepancy between this variable and THD::killed flag broke logic on SQL-layer and caused CPU and memory hogging. This patch tries to fix this problem by properly resetting this member. There is no test-case associated with this patch since it is hard to test for memory/CPU hogging conditions in our test-suite.

One possible scenario which exposed this problem was when thread which provided binlog dump to replication slave was implicitly/automatically killed when the same slave reconnected and started pulling data through different thread/connection. In 5.* versions memory hogging was added to CPU hogging. Moreover in those versions the problem also occured when one killed particular query in connection (using KILL QUERY) and later this connection had to wait for some table lock.
