Hi,
The current approach could be better because we want to use it on
Windows/MacOS and other systems. So, I've tried to develop another
strategy - detaching shmem and DSM blocks before executing the abort()
routine.
As I can see, it helps and reduces the size of the core file.

Hm, I'm not sure that's a reasonable way to scale things. Nor am I
really sure that's the right granularity.

I've seen those too, and I've had them myself. It's pretty frustrating
if a core dump makes the machine unusable for half an hour while said
coredump is being written out..
