The MS documentation states:


"All methods that are members of real-time interfaces must be implemented as 
non-blocking. They should not block, use paged memory, or call any blocking 
system routines. Note that most system routines are blocking"


This is most probably means that any kind of WaitXXX function should NOT be 
called explicitly or implicitly; so DeviceIoControl should be fine to use 
providing that a called driver completes a request synchronously


Do I miss / misinterpret something?
