Subject: perf-test: add test for reindexing after removal/renaming msgs
X-Git-Tag: archive/debian/0.33_rc0-1~70

perf-test: add test for reindexing after removal/renaming msgs

At this point it is a bit tricky to measure the performance increase
from the new message deletion code, since the same commit (9ad19e4)
that improved the performance also seems to have fixed a bug with an
uncaught Xapian exception triggered by this test.
