	This change again originates from the MinGW port. Since we don't
	have fork(2) on Windows, we must run the sideband demultiplexer
	in a thread.

If the rationale was "running in a thread is more natural on the
platform", I would understand it.

But "_must_ run because there is no fork(2)" solicits a "Huh?
How does Cygwin does it then?" from me.

You wont believe it: they start the currently running program again
and copy parents memory over into the child. Sometimes it fails.
If you want something scary:
