An alternative is to forkProcess and have the child
setResourceLimit and
then executeFile.
The documentation for forkProcess seems to say that Handle-based I/O
won't work in the child process. I need to communicate with the
program
I'm running via its standard input and output. Does this mean
forkProcess is out of the question?
No. What it means is that, if the child will continue to run in the
same Haskell program after forkProcess-ing, any open Handles won't
work right. You could fix this with handleToFd and fdToHandle, I
suspect, but it's irrelevant because you're going to executeFile
instead.
