o [Ncat] Wouldn't it be nice if we could support --exec (and maybe some sort of partial-emulated --sh-exec) on Windows? I think at least --exec can be done, because that function doesn't need the full generality of fork. Windows has a function called CreateProcess that looks to be sufficient. It is even set up to redirect input and output. One problem is that there is no recorded relationship between the parent and the child, so the child will not be killed automatically when the parent dies.

I don't know if these would be better or worse than CreateProcess. The _spawn*p functions use the PATH to look up the program, which is a partial emulation of --sh-exec. _spawn, _wspawn Functions http://msdn.microsoft.com/en-us/library/20y988d2(VS.71).aspx Cygwin FAQ: How is fork() implemented? http://cygwin.com/faq/faq-nochunks.html#faq.api.fork "In most cases, you are better off using the spawn family of calls if possible."
