 Priority:  major           |             Milestone:  someday
Component:  core libraries  |               Version:  4.13.0
 Keywords:                  |  Estimated difficulty:  trivial
----------------------------+--------------------------------
 On Windows, if you specify #t to nohang when calling process-wait, and the
 process is still running, you will get an error with a bogus error
 message. This is because process-wait uses WaitForSingleObject on Windows,
 and the result code WAIT_TIMEOUT is not handled, being treated as an error
 even though there was never an error in the first place. Attached is a
 patch to fix this bug.
