Under 3.x, ps(1) won't work right. : I'm not sure about gdb(1), it seems to use ptrace(2) these days. 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.
