As an experiment, I tried simply cutting the size of the test table 10X:
diff --git a/contrib/bloom/t/001_wal.pl b/contrib/bloom/t/001_wal.pl
index 1b319c9..566abf9 100644

This about halved the runtime of the TAP test, and it changed the coverage
footprint not at all according to lcov. (Said coverage is only marginally
better than what we get without running the bloom TAP test, AFAICT.)
It seems like some effort could be put into both shortening this test
and improving the amount of code it exercises.
