[plt-scheme] unit-based servlet vs module-based servlet?

Really?!  Not being familiar with the history of PLT scheme I have to say I
am surprised by the answer - I would have thought module is an older
concept.  Sounds like you are saying unit is slowly fading away?

Can module based servlets be loaded/unloaded on demand like unit-based
servlets?  And would badly written module servlet bring down the server?
Unit servlets appear to handle the above fine, but if module servlet also
works, then I am not sure if there are discernible differences (although
there are still more unit-servlet examples in the doc).

Thanks,
