Even that is risky, because if you have more than one instance of the
same executable running .. you will send a SIGTERM to all of them.

It is really much better to use a properly structured signal handler
within the project that can respond to SIGs and react appropriately and
if required close down in an orderly manner.  Note that this not a
simple answer, even postgresql to date still has the warning "don't kill
the postmaster!"

( Hi Benoit :-) hint hint gb.signal hint hint...)


Oh! and a final comment generally within this thread.   (IMO)

Never try to "kill" other processes from within a process.  Much too
messy and they may come back as zombies and do the same thing to you.
"kill"ing is for humans to do, not programs (there could be a corollary
of one of Asimovs laws there, possibly?)
