Looking at the page file on the hard drive, it is currently at
3,199,488KB, with an upper limit hard coded at 4,092MB (4,190,208KB).

Process Explorer:
Commit: 13.6GB (roughly   14,260,634KB)
Commit charge current:    14,254,748KB
Commit charge peak:       18,208,828KB

(recorded roughly 60 seconds after the above)
Task Manager:
PF Usage: 13.5GB (roughly 14,155,776KB)
Commit charge total:      14,258,808KB
Commit charge peak:       18,208,828KB
Physical memory total:    16,772,124KB
  "       " available:     3,798,000KB

Comparing the numbers between Process Explorer (now a Microsoft
product) and Task Manager on Windows 2003 x64 are very consistently
inconsistent.

-or-

 12,974,124KB physical memory in use
+ 3,199,488KB actual page file size
-------------
 16,173,612KB total memory usage

I *suspect* that the problem has to do with the memory page size being
4096KB for applications using large page support, rather than the
expected 4KB memory page size.  There is probably a bit of code in
Windows that does not yet recognize the change (this is a new feature
for Windows), either that or Microsoft should patent the approach of
jamming 14,254,748KB of data into a 3,199,488KB file.  :-)
