Isn't this the case for non-root ps'es? I'm not stating gospel here, but I
seem to recall that cmdline is unavailable for users because basically you'd
be able to get information you shouldn't necessarily have (mm.. dunno..
someone running fetchmail, specifying password, etc?)

Would a simple grep "search-string" `find /proc/some-regex` type thing work?
I guess it depends what information you want, from where.  Maybe you could
look at the ps script, and do a little #ifdef / #endif type thing? What I
mean is, in places where the ps script is obviously doing work (find, for
example), you could pass it a command-line option to cut that out, by
surrounding it with a conditional based on the command-line option. Because,
if ps is really taking that long, that probably means it's doing a lot of
work - speed it up by making it not do the work you don't need?

Cheers,

Alex.
