Make jobserver doesn't use named pipes, at least not on POSIX systems.
It does, however, require fully capable POSIX pipes, in particular ones
that are inherited by/shared across multiple processes and which can be
read from and written to by multiple processes simultaneously.

Not knowing anything about Windows that's about all I can say, except
that I _thought_ that there was at least one of the Windows
implementations of GNU make that fully supported parallel builds.
