Implement temporary streams.
A temporary stream functions as a memory stream until its size reaches
a preconfigured threshold value. Once it is reached, the stream storage
is automatically converted to a temporary file, and all data written so far
are transferred to the new storage. If the temporary file cannot be
created, the stream continues to operate in memory-based mode.
This stream type is intended to decrease the number of used file
descriptors.
