Yes, the bloat is worst on the x86 architecture; folks are working on
improvements.  The good news is that most of the extra stuff gets put
in its own section, which will never be paged into memory unless an
exception is actually thrown (so you pay a disk space cost for exceptions
but not nearly as much of a RAM cost).
