Like Daniel, I very much disagree that repeated dumping is
unimportant.  I think we want that capability restored very much, and
I think that it will be quite popular.  Having a working compiler as a
prerequisite for that would be a severe limitation.

Emacs can run without them, but it is quite limited, so I don't think
we should consider that a significant difference.

Well, by that measure we have a lot of "hassle" in Emacs already ;-)

I don't see why.  It's just one more file in libexec, that's all.

I wouldn't tell you to drop it, certainly not without knowing more
details, but in general I think we should not make any significant
design changes in how the pdumper works, until we (a) stabilize what
we have now (for now, a bug related to pdumper is reported roughly
every other day, so we still have some fallout), and (b) collect some
significant experience with it.  Based on that experience, we might
find good reasons to make some radical changes, but we are not there
yet, and I certainly don't see any serious problems with the current
design at this time, nothing that would justify yet another
significant change in that area.
