isthe time it would take to write a core that's huge because of shared buffers, but perhaps there's some way to avoid
writingthose? (That means the core won't help if the bug is due to something in a buffer, but that seems unlikely
enoughthat the tradeoff is worth it...)
Good idea. It seems the madvise() system call (with MADV_DONTDUMP) is exactly what's needed to avoid dumping shared
buffers.
