I had the opportunity to test chainlint.pl on an 8-core machine using
both Linux and Windows 10. The machine is more than a few years old,
though not nearly as old as my own development machine. Although
chainlint.pl checked all test definitions in the entire project in
less than one _second_ on Linux, it took two _minutes_ on Windows 10
on the same machine (using all 8 cores). Despite the fact that Perl is
run just once to check all test definitions -- unlike chainlint.sed
running 'sed' tens of thousands of times, chainlint.pl is still
painfully slow on Windows, so I certainly understand the desire to use
--no-chain-lint, at least on Windows.
