In GHCi it's a different matter, because the main thread is running GHCi itself, and all the expressions/statements typed at the prompt are run in forkIO'd threads (a new one for each statement, in fact). If you want a way to run command-line operations in the main thread, please submit a feature request. I'm not sure it can be done, but I'll look into it.
We already have a way: -fno-ghci-sandbox
I've removed all my explicit attempts to forkIO/forkOS and passed the command line flag you mention. I just tried this but it doesn't change the behavior in my example. Jason
