I regard this at least as a undesireable behaviour ;-) You may believe it or
not: I stumbled about this
problem some days ago while refactoring the code (it's not yet commited to
CVS).

A fast fix is to notify  m_task_is_available right after
m_thread_is_idle.notify_all();
in the resize method.

Best regards,
