  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

    Bug #28333 Test "flush" tries to create a new thread - on only one platform
    
    specify appropriate stack size for the 'query' thread

# This is a BitKeeper patch.  What follows are the unified diffs for the
