'Twas brillig, and the slithy toves

The problem that we attempt to address is the lack of backpressure
exacerbated by pushing more deferred frees on RCU. Before applying the
cleanup, it's easy for gem_ctx_create/files to push several hundred
thousand objects onto the RCU queues.

Something along those lines, thanks for the reminder.
