  Core-collapse supernovae emit on the order of 3x10^53 ergs in high-energy
neutrinos over a time of order 10 seconds, and so decrease their mass by about
0.2 solar mass. If the explosion is nearly spherically symmetric, there will be
little gravitational wave emission. Nevertheless, the sudden decrease of mass
of the progenitor may cause a change in the gravitational time delay of signals
from a nearby pulsar. We calculate the change in arrival times as successive
pulses pass through the neutrino shell at different times, and find that the
effect may be detectable in ideal circumstances.
