I'm getting intermittent "thread blocked indefinitely" errors with GHC 5.04.2. My program uses modules Concurrent and Posix heavily. In particular, I fork processes (now with GHC.Conc.forkProcess) and handle SIGCHLD signals to determine when the processes have finished. The symptoms seem similar to "evacuated object entered" problems I had with GHC 5.02 and an earlier version of my program. Any bugs or gotchas I should know about? Suggestions about how to collect information with which to debug this problem? (I've heard about +RTS -D1, IIRC, but have not tried it. Is a debugging RTS available? Is it possible for a mere mortal to build one?)
