raised.
I applied them again, and it worked well -- I agree that it is better to
leave the changes on constructing other quivers to the other patch, so we
have some time for discussions on design issues...
Replying to [comment:116 robertwb]:
> Lazily importing * is preferred, as it avoids stat'ing a new directory
and loading two new files (init.py and all.py). All this filesystem
activity seems to be one of the primary reasons for slow Sage startup time
(perhaps even more so than the execution of the .py files themselves) and
if we're going to try to fix that it's important to be careful about what
continues to be added.
> That being said, I have know idea what's up with volker-
desktop.stp.dias.ie . It's as if the file existed but was
incomplete/empty. Let's see if that continues to be a problem.
Thanks for your comments again. Are you suggesting to lazily importing * ?
We first did that but the patchbot didn't like it (i.e. some tests failed,
see Comments [comment:95] and [comment:97] above), that's why we then did
it another way.
