In #3432 it was decided to provide a way for disabling reporting timeouts and OOMs, see commit 1.
But these options are not described in documentation, see 2.

cfl: do not report OOMs
f152954 
luaL_loadbuffer_proto_test constantly reports OOM's. These fails
are false-positives and really annoying. An example of such fail
is below.
