I usually run into this with things like "rm * */*" or so.

It is system dependent. Here are a couple of things I found:
From "man errno":
E2BIG Argument list too long (POSIX.1)
and from "man sysconf":
ARG_MAX - _SC_ARG_MAX
The maximum length of the arguments to the exec(3) family of
functions. Must not be less than _POSIX_ARG_MAX (4096).
So one could query with sysconf and break things up into multiple
commands as needed.
In fact, until we have some sort of daemon that we can feed
arbitrarily-long lists to, that's what we should do.
