high load

MySQL server could crash if two or more threads would initiate query
cache resize at the moments very close in time.

The problem was introduced with the fix of bug 21051 in 5.0 and 5.1:
simultaneous query cache resizes would wait for the first one in
progress, but then each thread would try to finish the operation,
accessing the data that was already reset (attempt to dereference
'bins' pointer, which may be NULL already).

The solution is to check after synchronization if another thread has
done the reset already (test 'query_cache_size > 0' again).

No test case is provided because the bug is a subject to a race.

On windows IM aborted on assert once one
stoppped it. The reason is that we didn't
close the sockets on windows and therefore,
the listener thread wasn't able to finish.
This happened because we used close() call
for it. While on windows one should use
closesocket().
On other platfroms we have appropriate defines
for closesocket(), so this is the function which
should be used.

Note that we ignore CONCURRENT if LOAD DATA CONCURRENT is used from
inside a stored routine and MySQL is compiled with Query Cache support
(this is not in the manual).

The problem was that the condition test of "we are inside stored routine"
was reversed, thus CONCURRENT _worked only_ from stored routine.  The
solution is to use proper condition test.

No test case is provided because the test case would require a large
amount of input, and it's hard to tell is SELECT is really blocked or
just slow (subject to race).
