Subject: [PATCH] threads: fix WAIT_SYNC_INIT with a zero count

WAIT_SYNC_INIT(sync,0); WAIT_SYNC_RELEASE(sync);
hanged because sync->signaled was initialised to true, and
there is no reason to invoke WAIT_SYNC_SIGNALED(sync) before
WAIT_SYNC_RELEASE(sync)
this commit initializes sync->signaled to true unless the count is zero.

Thanks George for the review and guidance.
