OK, thanks -- the cache file is mmap'd by afsd and it depends on Windows
to manage what's in RAM.

The question arose because of a peculiarity of Task Manager under Windows NT.
It shows "memory usage" for afsd being about the size of the cache, but
"virtual memory" stays small.  So I guess Task Manager has a couple things
mixed up, or they have defined some terms strangely.
