Description
The crashtest-ipc and reftest-ipc suites. Recording doesn't seem to take unusually long, but I've had to abort two replay runs. I also don't remember noticing this before, but there seem to be a lot more -ipc tests enabled now (which is great!).

Research direction
Start by reproducing replay timing for the crashtest-ipc and reftest-ipc suites and compare it with recording time. Inspect how these suites are enabled and replayed, then identify the source of the excessive replay duration. Done means the slowdown is explained and replay performance is improved or the limiting behavior is documented.
