This is old stuff. I don't remember the details, nor did I investigate the 
whole thing. But the code seemed to assume that userspace are fully trusted, 
the remote Phonet nodes also. That does not work.

Protocol-level race conditions, API level race conditions, crashed remote 
peers, crashing user space processes, invalid API use, etc. All that needs to 
be dealt with safely. This is kernel code!
