Public bug reported:

dma installed, configured to deliver email via smarthost mandrillapp.com
crontab for local user, configured with cronjobs that outputs messages and thus 
should be delivered to the user, MAILTO="user") like this:

@hourly /usr/bin/task1
@hourly /usr/bin/task2

I get sendmail processes stuck (race condition?) consuming max CPU.
Currently there are two sendmail processes stuck at 48% CPU each for 7 hours. 
The command is /usr/sbin/sendmail -i -FCronDaemon -oem "user
/usr/sbin/sendmail links to /usr/sbin/dma

dma version is 0.9-1
architecture: amd64

My suspicion is that this is because of some race condition within dma,
since both processes seems to be created at the same point in time (same
timestamp). attaching strace gives nothing.

Is this a known bug? Are there any workarounds?
