Research direction

Start by investigating why rr replay requires perf-counter support on the described cloud servers, comparing the requirements for record and replay. The issue names no files, tests, or entry points; it is done when the requirement or a viable workaround is established and documented.

Written by the indexing model from the issue text.

Description

Hey, we are trying to run rr replay on some cloud servers (to replay traces recorded as a part of our debugger environment): I expected naively that only record needs to have special support for perf counters enabled, but it seems that it's needed for replay as well: is this a hard requirement, or is it something that might have a workaround for (i guess that you can't really control the execution in replays as well without it )
