- * xargs/xargs.c: Increase parallelism in mid-run with SIGUSR1;
- decrease it with SIGUSR2.
+ Control the parallelism of xargs with SIGUSR1 and SIGUSR2.
+ * doc/find.texi (Controlling Parallelism): New section describing
+ xargs -P, SIGUSR1 and SIGUSR2.
+ * xargs/xargs.1 (OPTIONS): Mention runtime adjustability of
+ parallelism in the paragraph on the -P option.
+ (SEE ALSO): refer to kill(1) and signal(7).
+ * xargs/xargs.c (proc_max): Since this is touched by a signal
+ handler, change the type to sig_atomic_t and the storage class to
+ volatile.
+ (increment_proc_max): Signal handler for SIGUSR1.
+ (decrement_proc_max): Signal handler for SIGUSR2.
+ (main): Install handlers for SIGUSR1 and SIGUSR2.
+ (wait_for_proc): If SIGUSR1 tells us that we now have an extra
+ free slot, continue to wait for other exited children, but don't
+ block.
* doc/find.texi, xargs/xargs.1, NEWS: Document SIGUSR1/2.
