I don't know if we are talking about the same "issues" (there have
been plenty of problems with building the font database), but building
the font database dropped from 45 minutes to less than a minute on my
machine. (OK, half an hour was due to a single font.) Reading the
whole font for each font in the system when building the database was
an overkill.

Some problems could be fixed per-font during font loading though. I'm
just speculating because I don't know the code. But doing an O(n^2)
comparison of glyph names on a font that covers the whole Unicode
should be avoided in principle.
