Updated patch with benchmark, now:

    https://80x24.org/spew/20171012191218.1624-1-e@80x24.org/raw

This hurts performance on fast filesystem, but these methods
are unlikely to be performance bottlenecks and (IMHO) avoiding
pathological slowdowns and stalls are more important.

benchmark results:
minimum results in each 3 measurements.
Execution time (sec)
name	trunk	built
file_chmod	0.591	0.801

Speedup ratio: compare with the result of `trunk' (greater is better)
name	built
file_chmod	0.737
