Assuming I understand the strict definitions (maybe someone should post
the strict definitions?) of "fully paged, virtual-memory environment"
the answer is yes.  You can probably satisfy yourself by looking at vmstat
and specifically try "vmstat -s".  It looks like this for instance:

	   20410 page cache hits
	    1963 page cache misses
	       0 procs swapped in
	       0 procs swapped out
	    1963 filesystem page reads
	       0 swap area page reads
	       0 swap area page writes
	     134 pages reclaimed from free list
	   22403 pages shared due to copy-on-write fork
	       2 pages shared due to cache hits
	   22636 shared pages copied
	 2868390 page faults
	  597987 cpu context switches
	 5980576 (non clock) device interrupts
	   81483 traps
	 5928438 system calls
