-Subject: fix open_[w]memstream behavior when no writes take place
-
-the specification for these functions requires that the buffer/size
-exposed to the caller be valid after any successful call to fflush or
-fclose on the stream. the implementation's approach is to update them
-only at flush time, but that misses the case where fflush or fclose is
-called without any writes having taken place, in which case the write
-flushing callback will not be called.
-
-to fix both the observable bug and the desired invariant, setup empty
-buffers at open time and fail the open operation if no memory is
-available.
