NGPT and process ids

I'm part of a team that is porting an application from Solaris to Linux. 
  One of the gotchas we're running into is that each thread on Linux 
(using the standard thread library) has its own process id (due to the 
unique Linux clone() syscall, etc.).

We're in the process of working out all of our process id related kinks, 
but I was wondering if NGPT maintained the normal pthread semantics of a 
single process id with multiple thread ids?  I'm planning to download 
the latest NGPT release and check things out myself, but any info from 
the mailing list would be appreciated.  Thanks,
