试题 :
1. In homework 1, for the uC/OSII on DOS, if we use the following TEST.C for
EX1_x86L, and run the resulting TEST.exe several instances simultaneously,
the timer in each instance will have more and more difference as time goes
by. Why and how do we fix this problem to shorten the time difference on
different uC/OSII instances?

TEST.exe: http://rswiki.csie.org/dokuwiki/_media/courses:100:ieos:test.exe
2. If we would port uC/OSII with a graphic window system on a virtualized
platform like Xen, what needs to be added or modified in uC/OSII to support
the window system and an accurate graphic clock? Note that no modification
on Xen is required.
