+       malloc/tst-mallocfork2: Use process-shared barriers.
+       * malloc/tst-mallocfork2.c: Switch to <support/test-driver.c>.
+       (signal_count, sigusr1_sender_pid): Remove.
+       (iterations): Define constant.
+       (shared): New variable.
+       (sigusr1_received): Update comment.
+       (sigusr1_handler): Do not send SIGSTOP to the sender process.
+       (signal_sender): Optional use barriers to avoid sending signals
+       during irrelevant times.
+       (do_it): Initialize variable shared.  Use xfork for error
+       checking.  Launch multiple SIGUSR1-sending subprocesses.  Limit
+       the iteration count, independent of signal delivery.  Check for
+       deadlocks in fork.  Introduce barriers for reducing signal
+       traffic.  Do not send SIGCONT to the SIGUSR1-sending processes;
+       replaced by the barriers.  Count signals during fork/free/malloc
+       and report them.
+       * malloc/Makefile (tst-mallocfork): Link with libpthread.
