sort: use mutexes, not spinlocks (avoid busy loop on blocked output)
Running a command like this on a multi-core system
sort < big-file | less
would peg all processors at near 100% utilization.
* src/sort.c: (struct merge_node) Change member lock to mutex.
All uses changed.
* tests/Makefile.am (XFAIL_TESTS): Remove definition, now that
this test passes once again. I.e., the sort-spinlock-abuse test
no longer fails.
* NEWS (Bug reports): Mention this.
