2014-08-04proc: Implement /proc/thread-self to point at the directory of the current ↵Eric W. Biederman
thread /proc/thread-self is derived from /proc/self. /proc/thread-self points to the directory in proc containing information about the current thread. This funtionality has been missing for a long time, and is tricky to implement in userspace as gettid() is not exported by glibc. More importantly this allows fixing defects in /proc/mounts and /proc/net where in a threaded application today they wind up being empty files when only the initial pthread has exited, causing problems for other threads.
