Probably you'd live with 512MB of swap. As for w/o swap? You need it
atleast to hear the disks trashing and know you have to ctrl-c the damn
process, if not anything else.

I have:
spiral:~# free
total used free shared buffers cached
Mem: 254572 89936 164636 0 4352 48016
-/+ buffers/cache: 37568 217004
Swap: 530136 0 530136

With X, netscape and a gcc running and doing quite fine.
