Summary: DB_File locking hangs on Ubuntu feisty / gutsy Linux

(opening a bug for this very annoying issue.)
Recently, the buildbot slaves running on Ubuntu platforms (t-feisty-561 and
jm-feisty) have been failing the 'make test' run, roughly once every couple
of days.
All these buildbot failures recently share these things in common:
- they're happening on Ubuntu Feisty or Gutsy systems (jm-feisty is running
Gutsy nowadays, despite the name)
- they are spamd tests
- they involve a spamd not giving its "server pid: \d+" line, which
indicates that it's ready to receive connections, in time (within
something like 3 minutes)
- upon examination, the spamd log looks like this:
[6910] dbg: rules: __MO_OL_25340 merged duplicates: __MO_OL_4EEDB
__MO_OL_7533E
[6910] dbg: conf: finish parsing

or

[13512] dbg: auto-whitelist: tie-ing to DB file of type DB_File R/W in

in other words, it seems to be hanging during the compile_now()
operation, while trying to access a Bayes DB, or an AWL DB.
two examples:
http://buildbot.spamassassin.org:8010/t-feisty-561/builds/270/step-test/0
http://buildbot.spamassassin.org:8010/t-feisty-561/builds/268/step-test/0
- it's *very* intermittent.
I initially thought it was a vmware-related issue, since t-feisty-561 is running
under vmware, but jm-feisty is a non-emulated Pentium M laptop.
I've tried to repro it under my new Dual Core Centrino Pro system here in work,
but after leaving the spamd test suite running in a loop overnight, there
have been no test failures :( it may be load-related, since that system is
much beefier than the others.
