Comment (by SimonKing):

 OK, if the echelon form thingy could simply be optimized by a better
 heuristics for choosing between padic and multimodular, and if it has not
 so much to do with coercion and cache, the question is whether we split
 the ticket into one for coercion and cache and another one for the echelon
 form.

 Just for information: With #12313, make ptest took 2155.0 seconds on my
 machine, with an update of the patch from here took 2152.6 seconds, but
 vanilla sage-5.2.beta3 took only 1991.3 seconds. Hence, there is indeed
 more work to do, and I think one should start by finding out what tests
 showed the worst regression.
