    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.
