pytest hangs on os.stat('//tox.ini') on cygwin. #2135
Description
Running the command pytest on cygwin, it hangs. Then I hit ctrl-C to get a stack trace.

KeyboardInterrupt
Running pytest in a debugger shows that pytest hangs on os.stat('//tox.ini').
'//xxx.yy' is an UNC path on windows, windows thinks tox.ini is a host name, causing pytest to hang.
