script like:

You can download my patch from

It is for erlier version, but it applies with offsets.

Can you please provide either a testcase for this so we can actually
reproduce this or a patch to fix it?

Updated version info. (assuming the last comment was based on the
snapshot)

Well, it seems that nothing has changed - on timeout it still does
longjmp without care of semaphores. Locks won't be freed so it will
hang. 
As I wrote few months ago, signal handler should only set EG(timeout)
flag.
