I've got myself a quite reproduceable crash: it occurs when a segmentation
fault/other crash occurs in the program StarOffice 5.0. Normally a program
dumping core wouldn't be a problem, but StarOffice is LinuxThreads, and runs
RFMEM|RFSIGSHARE :( Something goes wrong when a multi-kernel-threaded program
dies, and all members dump core at the same time. Init seems to be the context
in which the system panicked.o
