We used to block on all process access. This meant that shell
reading the keyboard input would block all VFS access making disk
accesses practically impossible. We now block only when it is
necessary :)
We now lock every function within Proccess, just to be sure.
Recursive lock allows us to use lock from the same thread even if
we already have the spinlock locked
We now read from a filesystem to user provided buffer.
Read sizes are determined by read call.
You should now get file descriptors and do reading through Process::current()
