I wouldn't blame your stomoach, Mumit.  The code is pretty opaque.  It's
begging for a complete rewrite.  I've wanted to rewrite the stuff in
fork.cc several times.  Every time I look at it I realize that, to do it
right, I'd have to modify the dl* stuff, too.

Thanks.

FYI, I wrote a 'strmatchcase' function a while ago which should be slightly
faster than strcasecmp.  I'll modify your patch to use this.
