   This is under Linux 0.99 pl 12.  There is something wrong here!
   I have 20 Meg of RAM.  Here are the current running processes.
   Following that list is the current amount of "free" memory I
   have.  This seems like a bug to me!  Suggestions?  I plan to
   try the pl10 kernel, as soon as I can grab a copy of it (I'll
   probably grab quiche's /usr/src/linux tomorrow.)

   > free
		total       used       free     shared    buffers
   Mem:         19052      12400       6652       1644      10288
   Swap:            0          0          0

No bug; Linux shares memory between the program pages and the buffer
cache.  Right now you have roughly 16 megabytes of memory available to
you; 6 megabytes isn't being used at all, and 10 megabytes is being used
for your buffer cache.  As you need more memory for running programs,
the buffer cache will automatically resize itself.
