Problem with parent shell killed along with child process

[Lars Nordin]

I have a program that when it recieves SIGTERM that it dies as it should but 
the problem is that the parent bash shell dies along with it too. Initially 
this was a pain during testing because I was logged out of the box - now I 
start another shell before testing.
I know that the program is using the default SIGTERM handler because I am 
writing it.
I know that it is not core-ing because "ulimit -c" is unlimited so a core 
should have been created if it was. 
Any ideas for where to look or what to try?
