The last time I checked to see how a core-dump was made on Linux, I
found that it was the "TRADITIONAL" method, i.e., the signal handler
does it. However, a newer review of the sources shows that there is
now an in-kernel dumper which is not the default, but can be compiled
in by defining USE_ELF_CORE_DUMP.
Although I have not tried it, it appears to provide the functionality
that you wish. It should (if it works), produce core.NNN where NNN is
the PID.
