I don't think this is really a problem nowadays. But if it is, let's
do it right: let's use a combination of 'touch' and 'ls -t' to
determine whether the file system supports 1-second time stamp
resolution. If we do it right, we can reduce the sleep time to 1
microsecond on most modern sytems.
In the mean time, sleeping for 1 second should suffice.
The goal here is to avoid a tradition of tests that sleep. Sleeping
slows things down. (And it's harder to parallelize. :-)
