You mean in the module "speak" thread, right, I didn't think about
that.  Actually, I've wondered why each and every module reimplements a
queueing system, more or less safely. I guess depending on the synthesis
it can be easier to write it one way or the other, but I believe we'd
gain from factorizing this.
