OK.  As you may be aware, this simplification was done because the
previous code's workload was too high (grepping through 600MB+ of text
per cgi call), and we at overseers@ weren't told otherwise.

Thanks for looking into it.  A few other possibilities to
ameliorate the impact of restoring the previous version:

- using xargs grep to use our extra cores, to reduce latency
- to impose a mod_qos concurrency limit on package-grep.cgi
