How fast/slow this implementation works with thousands of 
concurrent requests is of course untested. One DNS lookup may 
take one or even multiple seconds in the worst case. Since once
the internal call to GetAddrInfo() is fired cancelation of this
request won't free this thread for new task (it has to wait until
GetAddrInfo() returned before it is able to pick another request
from the request queue).
