Thanks for reporting, a quick search turns up https://bugs.launchpad.net/ubuntu/+source/dosemu/+bug/216398 which reads to be very similar to our issue here. I'm going to assign this to the maintainer of dosemu but the fault may lay elsewhere (kernel land), however I'm not suited to determine that.
Looks fixed in 1.4.1_pre20091009
