just to avoid any possible confusion: I emailed my reply to you and posted it to the list as well, but unfortunately I hit the wrong button so that my mail to you doesn't _say_ that it is a carbon copy. Sorry about the mess.
OK, thanks.
By the way: It's good to know I'm not the only one wrestling with Haskell's concurrency code. :-)
Yes. Its POSIX interface is, uhm, weird. I can't quite put my finger on it, but things like setting up a pipe to a child process's stdin just seem brittle and fragile with all sorts of weird errors. I can do this in my sleep in C, Perl, or Python but in Haskell I can barely make it work when I'm fully conscious :-) Oh also, I would very much appreciate Haskell interfaces to realpath() and readlink(). And a system/rawSystem that returns the waitpid() exit status like system(3) does, not just the exit code. (What happens if the process died because of a signal?) -- John
