It's a configure option (--enable-nsl-fork).  I assume GV's talking about
either djgpp (for which it hasn't been implemented) or cygwin.  Cancelling
a download is done by polling the keyboard.  Cancelling an ftp connect
(past the lookup stage) could probably be implemented similarly to the
nsl fork code, but it hasn't been much of an issue that I recall.

(patches are of interest ;-)
