Hmm. That's a good question. I would say it would "probably"
be ok. System calls in general should be ok.
The issue with vfork() is that the child has its own process
and related structures (file descriptors), but it is sharing
the parent's address space, so you don't want to do anything
that messes with memory beyond your local stack.

I was worried that vfork() might also share the descriptors.
