That something is broken inside Emacs, but Emacs doesn't tell what.
Did you build Emacs yourself? If so, could you please add a call to
GetLastError to sys_pipe (defined on w32.c), after the _pipe call, and
when it fails like that, see which error code it returns?
I was using Sean Sieger's build. Anyway, i update bzr repo to
"revno: 105425". Made following change:

if (rc == 0)

In gdb, the error number printed is always zero, even when this
file-error comes up. But it seems it would first give this error:
(file-error "Spawning child process" "resource temporarily unavailable")
After a while, starts to give following error:
(file-error "Creating process pipe" "no error")
Is it reaching some process number limit?

This is quite old, suggest to update to a newer version, to avoid
wasting energy on an old bug that was already fixed.
BTW, on my laptop, same OS, with a build back to Feburary, it has
no such problem.
