Comment:
I'm not able to reproduce it, but I've applied the following fix anyway:
{{{
Tue May 18 04:32:14 PDT 2010 Simon Marlow <[email protected]>
* Fix #4074 (I hope).
1. allow multiple threads to call startTimer()/stopTimer() pairs
2. disable the timer around fork() in forkProcess()
A corresponding change to the process package is required.
}}}
and the process package patch:
{{{
Tue May 18 09:36:17 BST 2010 Simon Marlow <[email protected]>
* Fix #4074: disable the timer signal around fork()
}}}
If you can test the fix that would be very helpful.
