threadDelay not ending
I've got some unit test code that forks off test processes using the 'system' function and then delays using 'threadDelay' to synchronize with the test process. This has worked fine until I upgraded to 6.4.2, now some of the 'threadDelay' calls never return - it's like they are stuck in limbo. Any ideas? What would have changed between 6.4 and 6.4.2 that would cause this behavior?

Re: threadDelay not ending
What is your environment? My project (which is about 70% Haskell) makes extensive use of threadDelay. I've not seen this behavior with 6.4.2. My environment is Linux using a recent 2.6 kernel. For obvious reasons I need to know whether there is a threadDelay issue here that is preparing to bite me.

Re: threadDelay not ending
I am running on Red Hat Enterprise Linux with the latest RH 2.6 kernel. This is very bizarre and I am having a hard time figuring out what is going on. I don't see any issues in the project code itself, just my unit tests. Rich Seth Kurtzberg wrote: What is your environment? My project (which is about 70% Haskell) makes extensive use of threadDelay.
