  In a previous paper (hep-th/0509067) using matrix model, we showed that
closed string tachyons can resolve spacelike singularity in one particular
class of Misner space (with anti-periodic boundary conditions for fermions
around the spatial circle). In this note, we show that for Misner space without
closed string tachyons, there also exists a mechanism to resolve the
singularity in the context of the matrix model, namely cosmological winding
string production. We show that here space and time also become noncommutative
due to these winding strings. Employing optical theorem, we study the bulk
boundary coupling by calculating the four-open-string cylinder amplitudes.
