Coverage remained the same at 99.034% when pulling 16fd4579ca37b00c577dfcbb6591a03c3db63b66 on isaacbrodsky:increase-fuzzer-runs into e5209fc714293008aeea5d7bd074d2ffd80d679b on uber:master.
It looks like 10,000 runs is taking too long for some fuzzer, so perhaps it's better to give it a time budget per-fuzzer.
Edit: looks like fuzzerGridDisk is where it is right now at 25 mins in.
Depends on #673, #671.
