We still have a problem of slow GC caused by many elements
of char-tables (mostly because of charset encoders). My
idea for fixing it is to somehow distinguish a char-table
that has only integer or (interned) symbol elements from the
other normal char-tables, and optimize mark_char_table for
it. But, at the moment, I don't have a time to work on it.
Perhaps we should open a new bug for that.
