__dpmi_yield seems like well in OK in Win98, but in WinNt, when I run may
program in a DOS command window, it appear a process called NTVDM that spend
all the CPU (not the procees related to the command prompt that spend no CPU
time in the NT Task Manager).
When the program is in backgroud, I feel that the system run slowly.

My version is Win NT 4.01, Service Pack 5.

Thank's for all.
