Well, there's no reason why this needs to be tied to a specific
release policy.  There's certainly no harm in implementing the
basic infrastructure of "make regtests-quick", leaving any debate
about exacty which files qualify for the "quick" test.

Problem is, somebody needs to sit down and do it.  Do you feel
like adding that?

I definitely think we should have stable releases much faster,
although I'd target 3-4 rather than simply every 3 months.  But
that won't happen until/unless the regression tests have much
better coverage.

This problem breaks down to:
- 10-20 hours of build system work.  (to add the regtests-quick
- 10-100 (?) hours of programmers to investigate+discuss code
  paths (?)
- 10-100 (?) hours of helpful users organizing and writing .ly
  files to cover all (? or most?) functionality
- possibly 10-20 hours of python programming to extend Patchy
  and/or the Paris university server
- somebody to organize the entire effort

I'm sadly not volunteering for any of those tasks.  I'm happy to
organize policy discussions about what to do with the results of
those tests (specifically for the 2.18 or 3.0 or other releases),
but I think we need some real effort on the fundamental
infrastructure before it makes sense to have policy discussions on
