Bug ID: 58830
           Summary: Battle.net installer occasionally hangs with ntsync
                    enabled
           Product: Wine
           Version: 10.16
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]

      Distribution: ---

Installing the official Battle.net 32-bit installer
(https://us.battle.net/download/getInstaller?os=win&installer=Battle.net-...)
does hang while downloading (a bit inconsistent depending on the machine, but
reproduces about 1/5 of the time).

In my testing, this only happens with ntsync, and interesting logging channels
(like +winsock,+sync,+server) make the bug basically non-reproducible.

As does a small NtDelayExecution of 1 microsecond in ws2_32 select().

There is another CEF crash right after the install succeeded; however, this is
independent of this bug.
