Test calls igt_fork() so for i915 requires offset allocation arbitration
(allocator in multiprocess mode) especially when same drm fd is used
in children. Dedicated thread (intel_allocator_multiprocess_start())
is required to be started on the very beginning to handle offset
allocations as well as stopping it (intel_allocator_multiprocess_stop())
before test exits.
