When running test008 in a loop, it will occasionally fail.  Investigation shows
that it fails to delete an entry known to exist in the database:

Here we can see a search that finds the entry:

conn=1028 op=433 SRCH base="dc=example,dc=com" scope=2 deref=0
filter="(cn=james*)"
conn=1028 op=433 SRCH attr=cn sn

A few lines further, this entry is deleted:

The resulting diff show the entry still exists in the generated database:
