All the files in tests/spec/glx_oml_sync_control/ already have this 
timeout ... except one, waitformsc.c. Since each test may have a 
different run time, I would rather want to keep it that way, to avoid 
surprises. How about adding the timeout in waitformsc.c:52?

Other than that, the commit message is a bit strange though. How about this?

glx_arb_sync_control/wait_for_msc: Add a missing timeout

This test requests via GLX to wait until a certain vertical retrace 
event (based on the Media Stream Counter, AKA MSC) before being 
unblocked by the X-Server. Since there can be bugs in the 
implementation, it is possible for the test to hang. Re-enforcing this 
idea is that all the other glx_arb_sync_control tests already have a 
timeout set.

This change adds a timeout to guard against this case and report a failure.
