Great.  I've integrated the patch, with some changes.  I await bug
reports.

I didn't like the duplication in cygwin.c and mingw.c, so I moved the
common stuff into windows.c (including terminate, which is worth
sharing).

Good.  I moved this code from the C runtime into the SML for the basis
library.

I added a note to mlton.org/MLtonProcess.

Are you referring to the "Problems" section on

	http://packages.qa.debian.org/m/mlton.html

which says that MLton is not in testing because of release critical
bugs?  Or something else?

We haven't yet even been able to reproduce bug #281701

If someone on this list can help out, we'd appreciate it.

Got it.  Thanks.
