Ahhh...That helps alot in understanding what's going on....although it's
raised another question, what are the 'units' for SWAP?  Here's the
'top' of my 'top' command - sorted by the SWAP column:

Cpu(s):  0.3% us,  0.3% sy,  0.0% ni, 99.3% id,  0.0% wa,  0.0% hi,
0.0% si
Mem:    255896k total,   253696k used,     2200k free,    25300k buffers
Swap:   265064k total,   105092k used,   159972k free,    71204k cached

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  SWAP

Hmmm....I've really gotta RTFM on this one, for info on the columns
VIRT, RES, SHR, SWAP - as I'm sure they hold the key..but don't seem to
'add up'.

Hmm...one thing that is weird....is that the SuSE 'System Monitor' that
shows 45% of memory free is lying to me!? 

thanks - Dave
