If I understand the code correctly, we have a .ini file read synchronously during startup. This is bad for performance. (not sure in which component this should go)
if a distribution.ini doesn't exist the only call we do is a file.exist(), the reads happen only in customized distributions.
Well, we don't want main thread I/O even in customized distributions, I assume.
IIRC some of these customizations do need to block startup, but I don't recall which (prefs?).

I think we've done as much as we're going to do here. We use a pref so we only check once.
