This had been discussed in some detail back when #2554 was first discussed, but AFAICT this change was never explicitly proposed. Makes a measurable difference to command execution times when writing to a host drive.

Where the host drives are accessed within WSL via the 9P protocol, disable memory-mapping output data. This provides a measurable perfmance boost when writing output images directly to the host system.
Relevant discussion in #2554.
