Subject/proc/*/mem weirdness
using plain Linux 2.2.2 I'd like to read the memory from another process using

# cat /proc/17940/mem
cat: /proc/17940/mem: No such process

pid 17940 _is_ running and working fine. reading /proc/*/mem fails for
_every_ PID in my system, except when I try /proc/self/, here I get

# cat /proc/self/mem
cat: /proc/self/mem: Permission denied


what's going on here? of course this all is done as root...
