            Bug ID: 91767
           Summary: wl_display_dispatch(_queue) documentation about thread
                    safeness is probably wrong
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: wayland
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: jadahl at gmail.com

There is documentation about wl_display_dispatch() states one may not mix
wl_display_dispatch(_queue) with wl_display_prepare_read() and friends, but
this is probably a common misconception, because internally,
wl_display_dispatch_queue() is implemented in the same way as one would use
wl_display_prepare_read() and friends, just without using those functions.

I have patches in progress that changes wl_display_dispatch_queue() to simply
use wl_display_prepare_read() and related API internally to make this more
obvious.
