Thank you for answering. Now there is only one problem: Assuming I could _not_ use 'bracket', 'withFile', 'finally' or any of the other usual scope-guarding techniques, what would I do? (The handle has to be passed up to the outside of the scope in which it was opened.) If I stored the handle in an 'MVar' and attached an MVar-finalizer to that, would that work better? Would the MVar's finalizer be run any sooner than the one attached to the handle anyway? Or can I explicitly trigger garbage collection somehow? Say, in case I receive an exception telling me that file descriptors are running out? Which exception would I even get in this case?
