  Log:
  SVN rev 181433 on 2008-08-08 19:39:11Z by jhb
  
  Fix the hangs reported with the real mode BTX:
  - I had errantly assumed that all user requests should run with interrupts
    enabled.  User requests for software interrupts, however, need to disable
    interrupts (and tracing) just like hardware interrupts.
  - Disable alignment checking when emulating a hardware interrupt as well
    (based on the description of the real mode operation of the 'INT'
    instruction in the IA-32 manuals).
  - Use constants for fields in %eflags.
