Yes, but if it is not safe, it is better to have a Tclae_SafeInit that 
returns TCL_ERROR.  That is positively stating that you are not safe, 
rather than leaving it to someone to infer that you are.

This is not the way that it worked on 9, right.  IIRC, you got a high 
level event in your event queue, which you had to service to get the 
event to be processed...

You can do a PID to PSN translation, there is an API for this in 
HIToolbox in Processes.h.  But I bet that tclsh doesn't have a psn.  It 
isn't registered with the WindowServer yet...
