[Bug 9142] wcmd can't open locked files

http://bugs.winehq.org/show_bug.cgi?id=9142

OK, that sounds reasonable, as everything would freeze.

Any other way to handle the EAGAIN? The create_file server code seems to do the
following:

1) Get access rights in server
2) Open/create the file in server
3) Save unix_fd in server

Why is step #2 done in the server at all? If the server must never block (which
sounds reasonable), then why is open() not executed in ntdll instead? If a
device does not implement O_NONBLOCK then it would end up blocking anyway.

Could it be changed to the following?:

1) Get access rights from server
2) Open/create file in ntdll
3) Save unix_fd in server

That should allow for the O_NONBLOCK to be removed, and might also free up the
server if there is a pending open().

Thanks,
