-// When we pass the MAX_BUFFER_LENGTH position, start checking for buffer overruns.
-// When we check, schedule the next check for MAX_BUFFER_LENGTH - (max(buffer lengths)),
-// since that's the earliest that a buffer overrun could occur. This way, checks are
-// as rare as required, but as often as necessary to ensure never crossing this bound.
-// Furthermore, buffers are only tested at most once per write(), so passing a very
-// large string into write() might have undesirable effects, but this is manageable by
-// the caller, so it is assumed to be safe. Thus, a call to write() may, in the extreme
-// edge case, result in creating at most one complete copy of the string passed in.
-// Set to Infinity to have unlimited buffers.
