These match what I see on my Cyrus Murder machines (linux 2.6) as well.

With 328 proxyd processes currently running on a frontend, top reports:

Tasks: 388 total,   1 running, 387 sleeping,   0 stopped,   0 zombie
Cpu(s): 20.4%us,  1.0%sy,  0.0%ni, 78.3%id,  0.0%wa,  0.1%hi,  0.2%si,  0.0%st
Mem:   2076724k total,   634260k used,  1442464k free,   162364k buffers
Swap:  2000052k total,        0k used,  2000052k free,   216200k cached

Which seems to roughly agree with a 2MB per proxyd rule-of-thumb.
