This isn't the first time I've wondered exactly which signal was meant
in a postmaster child-crash report.  Seems like it might be worth
expending some code on a symbolic translation, instead of just printing
the number.  That'd be easy enough (for common signal names) on Unix,
but has anyone got a suggestion how we might do something useful on
Windows?
