Process startup incurs a very large performance hit.  Yes, you
wouldn't want to be calling even a library compiler in a tight loop,
but still, it precludes doing at least semi-realtime things.  (though
the D compiler is so fast that it doesn't matter much anyway - see
h3r3tic's nucled)

Another thing having it as a library enables is much simpler IDE
integration, as you probably know already.  Furthermore, if the
compiler's interface is made flexible enough, you can also do some
really interesting things - have callbacks for imports which will
automatically fetch and install libraries that you don't already have,
for instance.  Things like DSSS would just become different frontends
for the compiler.
