Summary
ConstStaticCell could have been used to pass non-Send values to another thread
Details

ConstStaticCell<T> could have been used to pass non-Send values to another thread, because T was not required to be Send while ConstStaticCell is Send.

This was corrected by introducing a T: Send bound.
