It seem like I got a NFS-related bug here where a httpd process
hung in a uninterruptable wait (a disk operation, most likely). In order to
locate the problem I need the process' stack trace first.
gdb doesn't attach to the process for obvious reasons. Making a
crashdump doesn't inspire me at all.
The question is: is there a way of working with /proc entries? I.e.
is it possible to get all what I need from, say, /proc/<PID>/mem?
