Please run the test case under the debugger (compiled with -O0), and then in gdb when it bombs do the following commands.

{{{
(gdb) print original_mp
(gdb) print last_total_size_needed
(gdb) up
(gdb) print *mp
(gdb) where

Add information that is printed in the #832 assertion fails.  Also, don't actually assert a failure unless the node size got out of control.  Thus, if the estimate is too low, print an message and proceed if possible.  Addresses #832.

We rebalance at most one subtree per delete.

Insert and delete modified slightly to use tail recursion when simple.
