Bug#55001 Change in behavior: thread_concurrency (docs,
example files)
The system variable 'thread_concurrency' has been
(re-)enabled on all platforms, to prevent startup
errors.
'thread_concurrency' is unused and has no effect,
on any platform, in MySQL 5.1 and later versions. It
will be deprecated, and removed, in context of
worklog WL#5265
mysql-test/include/have_thread_concurrency.inc:
include/have_thread_concurrency.inc was only needed
to support platforms that didn't have the
thread_concurrency variable available. Since the
variable is now available on all platforms, the file
is removed.
