BSD process resource limit and priority functions
The BSD::Resource module provides the BSD process resource limit functions
getrusage(), getrlimit(), setrlimit() and the BSD process priority functions.
.
These are also available via core Perl but here the PRIO_* constants are
available: getpriority(), setpriority().
.
Also provided is times() which provides the same functionality as the one
in core Perl, only with better time resolution.
