Indeed, thats why I sent the follow up.
They aren't *dangerous* but they can be inconsistent across
OS. Plus some signals are wider in scope that the curent
process (eg ISTR Stop-A on a Sun can be broadcast to all
processes dependant on kernel settings) Also if a process
is run under the cotrol of a parent process interfering with
how that parent process deals with signals can result in
So the signals and signal handling mechanism per se is
not dangerous, simply that using them can create
"strangeness" in a system which can be a devil
Hopefully my other email clarified what I meant...
