I actually meant the earlier estimate to pertain solely to chuck
(though it probably applies to other audio applications too). Running
chuck across quite a few machines lately (plork powerbooks, windows
machines, and sometimes linux), latency has seemed consistently
inconsistent depending on the system.

It's hard to say (at least for me) - much depends on your sound card's
latency. ALSA, as far as I know, affords low latency. Which latency
are you concerned with? external MIDI/OSC events or audio I/O latency?
or something else? Sorry I can't provide a more precise answer.
Perhaps others here can?
