Description Jonas H. 2013-03-27 16:40:07 UTC 
journald takes up a LOT of CPU if some program repeatedly segfaults.

To reproduce: Let a program segfault every $interval (1s was sufficient for my computer). The program I used was

int main() { *((int*)0) = 123; }

http://cgit.freedesktop.org/systemd/systemd/commit/?id=34c10968 moves coredumps to a file on disk by default. Should fix the slowdowns.
