Race condition in 7.1.2?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello:

I've been writing a billing system with C++, ODBC, and PostgreSQL 7.1.2.
After I optimized my queries, I was surprised at how fast PostgreSQL can
swoop through 200,000 billing records. But I noticed, sometimes, the
final stage of my processing never completes, and PostgreSQL is spiralling
the CPU at almost 100%. I have to kill the process, which is thankfully
detected by my application which does a rollback.

Anyway, I'm quite sure it isn't my software that is causing this, because
if I do a simple vacuum after the rollback, and then run the same sequence
again, the final stage completes as quickly as I've come to expect.

I'm just wondering if there is a known race condition or something else
which would cause this phenomenon.

Thanks in advance.
