length(ls(envir = value, all.names = TRUE))
and the new code is considerably faster for regular cases,
but as you say is not correctly working for the special
RobjectsTables stuff.
Maybe this helps to find a last minute patch to that part in the
R 3.2.0 RC sources ?

RObjectTables freezes in R 3.2.0 RC on 32bit systems
We recently started noticing freezes that appear only on 32bit systems
(both linux and windows) with a relatively recent versions of R 3.2.0,
including the RC. It looks like the problem can be traced back to the use
of R_ObjectTables (see R_ext/Callbacks.h)
The problem is a bit difficult to reproduce because it does not appear on
x64 and because the official R interface to this functionality, the
