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.
