That could be a strategy but the actual goal is to find out why the
frontend holds on to so much memory.

The server process is using the precise GC in a 64-bit process (but with
limited type information as the way memory is allocated throws away some
of that info), so false pointers shouldn't occur too often. I have found
a number of stale pointers already, but there seem to be more.
