Currently executing statements will not be flushed, so your batch is perfectly safe (unless it's external, in which case all statements submitted after the flush will be re-parsed.) As Steve said, you will see a hit on CPU for a while, similar to one experienced when the instance is just started and the shared pool is initially populated. Other than that, no risks are known to be associated with this operation (at least to me,) except the obvious risk associated with change of system parameter like cursor_sharing.
