One common way, and my favorite, is to compile to some kind of bytecode or
wordcode, and use a dynamic optimiser to convert that to machine-code as
needed.  When code modification happens, it happens to the bytecode, and
when it's over the machine code can be deleted (or more accurately, the
bytecode can be tagged as unoptimised, so the next time it's executed it'll
be recompiled).
