Memory problem

[Vincent Lefevre <vincent@vinc17.org>]

On my PowerBook (2.6.9-powerpc kernel), top says:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND           
12457 lefevre   16   0  168m  64m  45m S  0.0 25.6 114:31.11 mozilla-bin       
12458 lefevre   16   0  168m  64m  45m S  0.0 25.6   0:00.21 mozilla-bin       
12459 lefevre   16   0  168m  64m  45m S  0.0 25.6   0:12.63 mozilla-bin       
12461 lefevre   16   0  168m  64m  45m S  0.0 25.6   0:25.27 mozilla-bin       
 1059 lefevre   16   0  168m  64m  45m S  0.0 25.6   0:00.03 mozilla-bin       

whereas on x86, I get only one instance of mozilla-bin (Mozilla is
compiled using the same .mozconfig). How can I fix that?

Also, my machine keeps on swapping very often (contrary to x86,
even with 128 MB RAM); top says:

Mem:    256100k total,   252596k used,     3504k free,     7028k buffers
Swap:   524280k total,   279740k used,   244540k free,    47852k cached

but I don't know why so much memory is used. Are there some tools
to know what processes use memory and so on (gmemusage seems to be
broken on the PowerPC, perhaps due to the reason explained in the
TODO file)?
