I've started to do the same thing to gcore(1), in order to make it
work properly with threaded applications. I've removed its dependency
on /proc/pid/mem, /proc/pid/regs, and /proc/pid/fpregs. However, it
still relies on /proc/pid/status and /proc/pid/map which are not
directly available via ptrace(2).
This would make the -s option to gcore redundant (since the process
will be stopped after attaching anyway). I don't know how useful a
core from a non-stopped process is, anyhow.
