does anyone have tips for reducing randomness in your programs while debugging? thinking of timing issues, random numbers, chaotic inputs, etc.
so far I have
- seed your RNG
- capture all input and run it a million times, and save the input once you find a version that fails
- use a record/replay debugger if you can (like rr)

Also: disable any helper threads that do stuff in the background (things like tcmalloc's page releaser or GC in languages with GC). They usually can be missing for the duration of a testcase with no ill effects (obviously, some bugs may be triggered by interaction with these).
