Originally in qemu when a IDE dma transfer is started which is triggered
by access to 0xc000 port in VMX, qemu will blocked there until it
finished. And during that block, there are extra dom switches between
dom0 and idle domain, and VMX can't be resumed. By making real IDE dma
tranfer run in another thread, qemu will return and VMX resume on time
and there are fewer cycle wasted.
