Subject: [Feature Request?] Inline compression of process core dumps

I've been trying to find a method for compressing process core dumps 
before they hit disk.

I ask because we've got some fairly large UML processes (1GB for some), 
and we're trying to capture dumps to help Jeff debug an evasive bug. 
Our systems use a small root partition and most of the other disk 
resources on the host are allocated towards the UMLs.

There are userspace solutions to this problem:  allowing the 
uncompressed core dump to spin out to disk and then coming in afterwards 
and doing the compression, or maybe even a compressed filesystem where 
the core dumps land, but I just thought I'd throw this out there since 
it seems it would be a useful feature :)

Thanks,
-Chris
