IMCC is a much bigger problem here.
I'm not sure it does, or at least that it should. (Though if people
play interesting games with register set swapping it could, I suppose)
Apart from such tricks:

So first some numbers WRT speed:

Cachegrind of course states that the memcpy in the register push/pop is
the culprit, the pushN/popN take almost double the time of the other.

Saving and restoring all the registers is obviously a waste of time in
many cases.
This sentence seems to contradict pdd03 - not that's a waste but ...

The compiler can't decide on not to emit saveall/restoreall - we are
talking here about Parrot calling conventions and the caller saves all.
The compiler may omit the saveall/restoreall on the last function

Second, I see that the registers themselves are in the context structure.
I think this may be a good part of our speed problem with taking
continuations. Now, continuations should *not* restore the registers, so
this strikes me as an incorrect
Okay, at the moment I'm working on getting an implementation of
classes and objects working. I'm also taking a look at calling speed,
as I'd really like to not suck with our call times. :)
First off, the core stuff looks good. I'd not really looked at it
until now, but now that I have, well...

Are the register stacks saved with the continuation?
Yes, of course they are.
Er, yeah, um.. Everybody, forget everything I just said %-)
