5312063138 std.Io.Threaded: work around parking futex bug 
This commit should be reverted - it's testing a hypothesis that Windows
is deadlocking due to bug in the implementation of

83abd73801 Windows: Support directory handle for cwd instead of string for Child.process 
This implementation is a bit of a hacky workaround, as we use a ntdll
API to grab the full path of the directory handle. As far as I can tell
this might be the only solution to the problem, as
kernel32.CreateProcessW takes a directory path as a string only.

I might be wrong though as haven't researched the problem thoroughly.

25aef0dd87 std.Io.Threaded: rework file reading to observe nonblocking flag 
- batchAwaitAsync does blocking reads with NtReadFile (no APC, no event)
  when the nonblocking flag is unset, but still takes advantage of
  APCs when nonblocking flag is set.
- batchAwaitConcurrent returns error.ConcurrencyUnavailable when it
  encounters a file_read_streaming operation on a file in blocking mode.
- fileReadStreaming avoids pointlessly checking sync cancelation status
  when nonblocking flag is set, uses an APC with a done flag, and waits
  on that value to change in NtDelayExecution before returning.
- fix incorrect use of NtCancelIoFile (ntdll function prototype was
  wrong, leading to misuse)

39a6d5d1c5 std.Io.File: add non-blocking flag 
On Windows, we need to know ahead of time whether a file was opened in
synchronous mode or asynchronous mode. There may be advantages to

3320e6a1ae std.Io.Threaded.batchWait better fix for any_done 
It is legal to call batchWait with already completed operations in the
ring. In such case, we need to avoid waiting in the syscall. The
any_done flag was a poor way of tracking state we already have: whether
the completion queue is empty.

This problem affects the posix poll implementation as well.

Thanks again to jacobly for finding the problem.
