  Modified:    sys/miscfs/procfs  procfs.h procfs_subr.c
  Log:
  Implement locking for pfs nodes, when at the leaf.  Concurrent access
  to information from a single process causes hangs.  Specifically, this
  fixes problems (hangs) with concurrent ps commands, when the system is under
  heavy memory load.
