Hi, I managed to trace the problem to PTY handling on Mac OS X. It was not a problem of setsid, but the order of closing file descriptors. Also, I reverted the double-forking patch, as it was not the right solution. I'm including the patch, which holds the explanation of the problem. Bjorn has already applied this patch to MacVim.
