[Info-vax] High resolution per-process CPU consumption statistics

Would like to be able to measure process CPU consumed during specified 
continuous sections of processing.  Only interested in CPU-intensive 
sections so USER mode consumed relevant.  Imagine inserting calls at the 
beginning and ending of those sections with a magic number representing 
CPU consumption/delta/whatever made available.

As some of these CPU-intensive code sections are short duration the 
granularity needs to be quite fine.  The likes of JPI$_CPUTIM and 
LIB$STAT_TIMER (10mS) seem unsuitable.

Prepared for non- USER mode code.  This is only for ad hoc developmental 
insight and not general use.  Needs to accommodate Alpha and/or Itanium 
(and/or x86-64 :-)

And, of course, any other suggestion.

As always, TIA.
