Tcl under conditions of high memory usage.

Hi,

I have at various times had core dumps with Tcl under conditions of
fairly high memory usage, both on windows & FreeBSD.
I hardly expect applications to run properly when there is little free
memory - but is it normal for the app to just crash?
I sometimes get an error reported, something like: can't allocate
memory for tcl_listobj

Other daemons & applications will just grind their way along slowly -
whilst the system uses it's swap space heavily - but my Tcl daemons
just crash, well before the machine seems really overloaded.

Sorry for the lack of specific figures and scientific analysis - It's
just an impression I get about the behaviour of Tcl under load at this
stage, and I'd like to know what the expected behaviour is, or if
others have similar experiences.

(running FreeBSD, Tcl8.5b3 at the moment)

Cheers,
Julian
