Ok, so how're we going to do all the async js stuff we'll have to start doing
properly soon?  Tbh I'm not sure how much I'm attached to the multiple process
idea other than it means js can go pop and we don't... but we *need* to sort
out async js soon.  Unfortunately websites are becoming increasingly reliant on
ajax being genuinely async and that's before we get to websockets etc.
With 2 processes it means that we can start with a simple interface with pipes
and select as now.  With 1 we'll need to do thread-safe programming to make this
fly properly.  It's not impossible but we'll have to make a bunch of changes to
make the existing code properly thread-safe to make that work, or have some way
to run duktape in a mode where it only does a certain amount of instructions and
use select/poll/some event loop to allow io, comms and js to work together...
Honestly I'm not sure what the right design is yet. I've been, unfortunately,
rather busy and unable to do much on edbrowse recently so I'm still catching up
with things.
That being said, this variable, plus the fact that we've made the switch to
duktape (well done for that, sorry I ran out of time to help) gives us a
mechanism to may be play with some sort of different model for running js.

Cheers,
Adam.
