Subject: [Caml-list] SIGTERM signal in multithreaded application
Dear All

while working on  POESIA - www.poesia-filter.org ; see CVS code under
http://www2.poesia-filter.org:8000/ 

I notice that (with the native ocamlopt 3.06 compiler) on my Linux/x86
Debian/Sid (2.4.20 kernel, glibc 2.3.1)

When a multithreaded process is sent a SIGTERM or SIGINT signal
(either by a ^C on the terminal, or by the kill command) every thread
executes the signal handler with a negative signal number, and the
Sys.sigterm is -11 (negative eleven)

Is it possible to code so that only the main thread recieves a SIGTERM
signal and not all threads? Is this a Linux pthread or a OCaml runtime
system issue?

(I don't master all the subtilities of Linux threads, in particular
w.r.t signals).
