What rr does
This is incredible!<p>For those that have used it, how useful it is for debugging multithreading heisenbugs? Can I let a process run under rr for days, wait until it crashes to due a heisenbug, and replay the trace without rr having to go through days of recording? i.e. is it possible to fast forward the trace, somehow?<p>(I nerd sniped myself a bit here, wondering how fast forwarding could be implemented. I think it might be achievable with periodic process memory snapshots and incremental traces.)
