Hi Maxin and Marteens,

Nesting makes sense: it is useful to let the system know where to go when the
wait finish. Rebol handle this with nested wait. This is a standard behaviour
used by the modal system which is usually called from event code.
And this does not crash Rebol as Holger one time said (at least seems to me).
The crash pointed by Maxim is already in tracker (#84): you can see what Carl
says about it in the Notes section of the bug.
Obviously this can be handled in another way, building a chain of filter
function in one wait loop, but this is not the actual rebol implementation.
