    I wanted to ask this for some time - would it be possible to change this
    in some 'soft' way? Maybe using SoftReferences (not Weak) would help, so
    that a pending OOM can be avoided in situations where there really is only
    one session and lots of GC pressure, or something like that. IMHO a hard
    upper limit sounds wrong for a per-context setting, so something more
    graceful would be nice. Hard? Easy? Wrong idea? :)
