I haven't followed this thread, so I'm sorry if it's off-topic. But I have
long been wondering what the consensus is wrt. finalization and things like
signals, OS-exceptions, C abort() &c.

Should the Runtime go out of its way to finalize things, or should the
programmer write signal handlers, OS-exception handlers, and override
abort() &c ?

Since I am using GNAT under OS/2, where finalization isn't done when a signal
is raised (eg. Ctrl-C/SIG_BREAK) I would be interested in what consensus is
and what other compilers do.

Is it at all possible to _ensure_ that finalization gets done when interfacing
with C ? (when not counting power/hardware failures)

Thanks in advance for any info...
