  A "supersolid" -- a crystal that exhibits an off-diagonal long-range order
and a superflow -- has been a subject of much research since its first proposal
[Andreev and Lifshitz 1969], but has not been realized as a ground state of
short-range interacting bosons in a continuum. In this note I point out a
simple and generic mechanism for a thermally-driven reentrant supersolidity,
and discuss challenges of experimental realization of this idea. In the limit
of bosons in a periodic potential, this mechanism reduces to a {\em reentrant}
low-temperature normal-superfluid transition, that should be accessible to
simulations and in current experiments on bosonic atoms in an optical periodic
potential.
