@itsbilal @RaduBerinde - you were looking at long-running Download operations before, right? should we do something specific to -race builds?

metamorphic: fix WAL failover config generation
9b491cf 
Previously it was possible for the metamorphic test to generate an invalid WAL
failover configuration where the healthy interval was too long for the given
probe interval, resulting in a healthy interval that could never be satisfied
with the fixed 120-entry probe history.

Informs cockroachdb#3618.

Looking at the latest failure above, random-015 has block_size=4 and target_file_size=12 which leads to 20k+ tables created. I will try to repro with those ops locally to see if it's just expected slowness or something else.

metamorphic: bump timeout for Compact/Download/NewSnapshot
ece2f64 
Bump up the timeout for these ops, which can be very slow if both the
block size and target file size are small and we end up with a ton of
tiny tables.
