hi,

this patch fixes a ssl migration hang issue: when another VM started by
xend, the spawned qemu process will keep the p2cwrite file descriptor open.
Thus there will be two open descriptors associated with the write end of the
pipe. Then when read end of the pipe only reach the EOF when the qemu process
has terminated.

thanks,

zhigang
