Well, yes, you have an infinite recursion similar to a classical stack 
overflow, only in this instance it is processes that you overflow. That 
last line invokes a new shell process to run the script, and waits for 
said process to exit. What are you *expecting* to happen? Your script 
fails to illustrate any reasonable problem.

Hmm, that's a lot of lines for a .sig, especially rather spammy ones. If 
those are yours, you might want to consider a more polite (read: 
shorter) signature.
