LWM is easily co= nfused with "low water mark", which is the opposite of what the LWM does. N= ames are always open for discussion, so I won't object to it. Yes it is a threshold, and yes it is often called a watermark. I think we can get more ideas and votes about the naming. Please let's conclude on a short name which can be inserted easily in function names.
