  We argue that any violent galactic winds following early epoch of star bursts
would significantly weaken the potentials of galaxies, and leave lasting
signatures such as a lowered dark halo density and preferentially
radial/escaping orbits for halo tracers such as globular clusters. A galaxy is
disintegrated if more than half of its dynamical mass is blown off. The
presence of dense halos in galaxies and the absence of intergalactic/escaping
globulars should imply an upper limit on the amount of baryons lost in galactic
winds around 4% of the total mass of the galaxy. This translates to limits on
the baryons participating the early star bursts and baryons locked in stellar
remnents, such as white dwarfs. The amount of halo white dwarfs claimed in
recent proper motion searches and microlensing observations in the Galactic
halo are too high to be consistent with our dynamical upper limits. Similar
arguments also imply upper limits for the amount of neutron stars and stellar
black holes, in galaxy halos. Nevertheless, a milder outflow is desirable,
especially in dwarf galaxies, both for lowering their cold dark matter central
density and for injecting metals to the intergalactic medium.
