Not the inventor. Fixer and sometime feature-adder, perhaps. :-)

Probably not. :-)

It does two things:

1.  It closes *all* open sockets. This could be a problem if you have  
sockets open for other reasons.

2. It deletes all its own scipt local variables. This includes any  
urlCache content. This shouldn't be a problem, but a few problems  
have been reported when libUrlResetAll is called and then, in the  
same handler, a subsequent url call will fail. It's as if the engine  
doesn't delete the script locals synchronously, but decides to wipe  
them out just when the next url call sets them.

In most cases, neither of these will be a problem. Your Stop button  
example should be fine. (Except for any lost cache data.)
