Here, -f means force, using Windows native methods to kill the process
when cygwin signal handling seems to be stuck.

cgf has been known to add some sarcastic humor to this list - lately
there have been a lot of (unfounded) guesses by newbies that
their dual core is causing cygwin fork problems; but the real root
of the problem is that they had a bad driver pre-installed by Dell
that was corrupting kernel memory. In short, dual cores are
not the real problem, (neither is repeatedly reinstalling cygwin,
or any other number of trite suggestions that cgf offers
tongue-in-cheek based on the newbie fad of the week). But
it takes a regular reader of the list to pick up on some of this
humor :) The use of ! is supposed to be a clue!

Also bear in mind that cgf has been trying to improve cygwin
signal emulation; trying the latest snapshot will help in this
regards: either it will solve your problem, or you can give
useful feedback to the list that there is still an issue.
The biggest problem that cgf faces is that without simple
test cases, it is nearly impossible to determine where the
bug lies, and he doesn't have time to filter large programs
down to simple cases.
