even then you only get 5000 boxes defined ...
Well, that's because I was impatient and have changed a 1000000 to a
1000 ;-)
you can reset the storag
of course but you still have 5000 hash entries (mening \undefined then)
with names like TempBox*-*
That's very good info, thanks!

when we would reset the allocator count then \oof would still be ok but
its slot would be reallocated at some point by \newlocalbox
I hope you don't mind explaining this further, as I'm lost.
1. I was unable to produce this effect. Should it happen with the
\newlocalbox defined in this thread, or some hypothetical \newlocalbox
(which would share the allocation counter with \newbox?). I tried both
your \newlocalbox and elocalloc's \locbox, and didn't manage to
reallocate \oof's register.
But maybe this question is bogus, as:
2. I don't understand why it is important to use \newbox within
\setbox\foo\hbox{...} Don't we get the same result in the following?
\starttext
\bgroup
\newlocalbox\foo
\setbox\foo\hbox\bgroup
bar
\egroup
\ifdefined\oof\else\newbox\oof\fi
\global\setbox\oof\hbox{foo}
\egroup
\box\oof
\stoptext
the difference is that a next \newbox\oof will report that \off is
already defined (so no new box will be allocated unless you \relax \foo)
while \newlocalbox\foo will happily reuse \foo and not report a message
(as you use it local \foo is also defined as local while \oof is global)
