    Here's what I have been able to determine about nolabels:

    When nolabels is true, input and output labels are generated
    but not appended to labels, the list of all input and output
    labels. kill (labels) kills the labels on the labels list,
    but does not kill any labels generated since nolabels was
    assigned true.

    The stated rationale for nolabels (in the pre 5.9.2 docs) is
    to save memory by not binding labels. We could either (1)
    fix the current behavior -- search for instances of
    makelabel and put in a test to prevent binding the label
    when $nolabels is true; I guess this will interfere with the
    display code. Or (2) just drop the nolabels stuff. One can
    always do kill(labels) to free up memory.

    The nolabels code was fixed somewhere between 5.9.2 and
    5.9.3; nolabels:true now has the expected behavior.
