Question about coroutine, possible cause of context leak.

[deflinhec]

I'm aware of the LState NewThread function propagate a new context which never be cancel.

gopher-lua/state.go

Line 1563 in d212719

thread.ctx, f = context.WithCancel(ls.ctx)

gopher-lua/coroutinelib.go

Line 21 in d212719

newthread, _ := L.NewThread()

I'm current working on a service which use the latest version of gopher-lua, according to the graph, which generate from /pprof/heap, It seems to be a context leak with the coroutine module?

12 hours Memory usage deployed on Kubernetes, service get restarts after a peroid of time.
