>From a user perspective, I think that there are two reasons we might
want to switch off native-comp.
The first is because it's broken or providing buggy behaviour. In the
extreme, and if I understand the build process fully, I guess this is
impossible to switch of in a binary distribution, because some
native-comp happens before dumping. Other than that, we can "switch off"
native-comp by just deleting the *eln files, right, or otherwise
preventing their loading. In practice, I think this is a minor
motivation; if we discover bugs in the native-comp, they would be fixed
by making another release.
The second reason is that the initial compilation takes quite a lot of
CPU. I wouldn't like that to happen while my laptop where in battery
power, for instance. At the moment, it's possible to drop the number of
jobs that native-comp uses. I don't think that there is a way to drop
this to zero at the moment. Probably, we need that.
