I haven't looked very thoroughly yet, but I just wanted to remark on
the cryptic identifiers used in filenames and also in the code. For
example there is a file core/dv.rkt which appears to implement some
kind of automatically resizing/growing vector, although I don't know
how to map that to `dv'. Similarly there is a core/erl.rkt that seems
to be implementing some thread management. (I think that each
signal/behavior is implemented as a separate thread). No idea what
`erl' is supposed to mean. Anybody have any idea what these letters
stand for?
