checking memory and cpu consumption of procs

[Voon, Ton]

Dave,

I've tried to run your program on Solaris but I'm not having any joy. I
managed to add in the poll checks for configure, but when running, it goes
into an infinite loop. It seems that the line:

n = poll (fdarray, 2, INFTIM);

is returning 2, but the condition

(fdarray[0].revents & readable)

is not true and so the read_size never gets set to 0 and the loop never
ends.

I don't know if this is a Solaris limitation (uname: SunOS 2.6).

Is there any particular reason you wanted to use poll? I think for a simple
subcommand, the spopen and fgets used in check_procs is probably sufficient.
