Linux kernel patch:
To get useful core dumps under Linux it is necessary to get the
kernel to write the offending thread written to disk. There is
a patch, contrib/linux/coredump-patch, which achieves this.
Linux systems do not provide useful core dumps for multithreaded
programs unless the kernel patch in contrib/linux/coredump-patch
has been applied. We recommend all Linux users to install this
patch so that any server crashes can be properly diagnosed.
