Test "flush" works everywhere, including embedded,
*except* for Debian-PPC-embedded:

flush                          [ fail ]

Errors are (from /PATH/mysqltest-time) :
mysqltest: At line 26: Cannot start new thread for query
(the last lines may be the most important ones)
Result from queries before failure can be found in /PATH/mysql-test/var/log/flush.log

Line 26 is the closing brace '}' of the while loop in the test file.

How to repeat:
Run embedded tests on that host.

  Bug #28333 Test "flush" tries to create a new thread - on only one platform
  on PPC/Debian Linux default stack size for a thread is too big.
  As we use default thread settings in mysqltest, the
  thread creation fails if we create lots of threads (as it
  happens in flush.test). So now stack size is explicitly specified
  for the mysqltest

Noted in 5.0.44, 5.1.20 changelogs.

mysqltest used a too-large stack size on PPC/Debian Linux, causing
thread-creation failure for tests that use many threads.
