RE: ngpt-2.2.0 & shared memory???

Thank you!

Sorry, don't know how I missed that little tidbit!  It's clearly documented.  

Threaded app performance is MUCH better and more in line with what I've grown used to on AIX, HP, and Sun systems.  (LWPs anyone???)

Many many thanks again and sorry for the wasted bandwidth.
