        Under 5.2.x, measuring the `time` of a subshell -- `time ( sleep 1 )` 
for example -- doesn't display any timing information,
         whereas `5.1.x` and before did.

Thanks for the report. It's an easy fix; bash was optimizing away the fork
and therefore not printing the timing information.
