Hm, looking here:

and here:

It looks like a) proc/self/exe is going to be there for almost all (if 
not indeed all) modern Linux distros,
and there are methods to get it for the BSDs and OSX.  If someone knows 
a Linux setup where Pd
can be used where "proc/self/exe" wouldn't work, let me know.

That's a lot of ifdefs, but we might as well fill out pd_getdirname and 
then it's easy to hook in through
[pdinfo].  If nothing else, this would be useful for 

That said, launching another Pd from inside Pd this is the wrong 
solution to the OP's problem.  That's
kind of the point of [pd~].  Max- Are you experiencing dropouts from the 
subprocess stalling, or are you saying you're trying to avoid the 
possibility of dropouts.  If it's the latter, then I'm having a hard 
time figuring out how two Pds connected through netsend would avoid 
dropouts.  Also, what causes the freezes?
