Well, you've now given us a new measurement for how slow is "too slow" --
when bootstrapping one snapshot runs into the following snapshot, we know
we've hit rock bottom. :-)

I wish I could find that paper where some researchers wrote their linker
to do its normal work on the first invocation, then fork off and run
as a daemon. Future relinks contacted the linker daemon. Since there
was a symbol table and whatnot already constructed, link time dropped
*significantly*. I've often wondered what that would be like for GCC and
compilation time; a little gccd running during the length of a project
Boy, if only gld and gas supported more platforms. Just imagine all of the
Nifty Things[tm] we could do if we required binutils to be present rather
than relying on the native tools. (Of course, if we did that, we would
ship binutils along with gcc.) We could share the same symbol table from
the preprocessor all the way to the linker, for example. But until then,
that's all we can do: just imagining. :-)
