A quick audit of the code shows that truss and gcore will stop
working, since they use procfs.  I thought that ps used procfs to get
some command args, but come to think of it, it didn't show up in my
grep.

gdb seems to use the proc/pid/mem file, but I didn't look closely to
see if that was ifdef'd out or not.
