We just added a test to try and get srch compaction stuck by having an
input file continue at a specific offset. To exercise the bug the test
needs to perform 6 compactions. It needs to merge 4 sets of logs into 4
sorted files, it needs to make partial progress merging those 4 sorted
files into another file, and then finall attempt to continue compacting
from the partial progress offset.
The first version of the test didn't necessarily ensure that these
compactions happened. It created far too many log files then just
waited for time to pass. If the host was slow then the mounts may not
make it through the initial logs to try and compact the sorted files.
The triggers wouldn't fire and the test would fail.
These changes much more carefully orchestrate and watch the various
steps of compaction to make sure that we trigger the bug.
