are there any known issues
with file handles/descriptors in ghc-compiled executables?
My program has a lot of calls to System.Process.runInteractiveProcess
and I'm running into unpredictable behaviour (sometimes the program
just silently dies, sometimes it gets stuck)
The handles I get correspond to file descriptors in the OS?
Could there be any conflicts? (Like not enough available,
or re-used to early etc.)
Or perhaps you see anything that's wrong with my code here
I'm compiling this with -threaded, but running with -N1.
Of course, terminateProcess is another source of uncertainty here.
(Sometimes it takes several seconds until the external process dies.)
Any hints appreciated. - J.W.
