ok, I've comitted a change to remove the signal mask prior to calling
exec. I'd appreciate it if Whistle could test it. I'm not sure this
is causing the problem, but it is the only thing I can think of.

:> Anyone know for sure?
:
:It does not. manpage for signal(3):
:
: When a process which has installed signal handlers forks, the
: child process inherits the signals. All caught signals may be
: reset to their default action by a call to the execve(2) function;
: ignored signals remain ignored.
:
:Note that this affects any background program run via "nohup" also. If
:you run "nohup program &", don't expect to be able to kill -HUP it
:later. This was discussed a little on the mysql mailinglist, when
:FreeBSD people noticed that they couldn't kill the server (mysql uses
:-QUIT to exit, and nohup blocks HUP and QUIT).
