Upgraded to 4.67.6, MailScanner scans a batch then hangs at 100 percent CPU

[Steve Crumley]

OK, I'm stuck.  I'm running CentOS 4.6, sendmail 8.13.1 and spamassassin
3.2.4.  I've disabled mailwatch, spamassassin, sql blacklist, and AV.  I
also set the number of child processes to 1.  MailScanner starts ok,
scans a batch of messages ok, then maxes out the cpu and never picks up
another batch of mail.

Here is the debug output:

MailScanner --debug
In Debugging mode, not forking...
