Well the profile is definitely not flat.

I'm using the profiling tools and Network.accept is apparently the major 
offender using both -hc and -hr profiles.  I take it this implies that 
the products of this function are being retained elsewhere.  I do pass 
the handle off to another thread via forking - this shouldn't be an 
issue should it?  Another retainer involves SYSTEM and Network.accept - 
what exactly does SYSTEM mean?
