The PR_DUMPABLE flag causes the pid related paths of the proc file system to be 
owned by ROOT.
    
    The implementation of pthread_set/getname_np however needs access to  
/proc/<pid>/task/<tid>/comm.  If PR_DUMPABLE is false this implementation is 
locked out.
    
    This patch installs a special permission function for the file "comm"  that 
grants read and write access to all threads of the same group  regardless of 
the ownership of the inode.  For all other threads the  function falls back to 
the generic inode permission check.
