65,664 is 65,536 + 128. builtins/psize.sh runs "./psize.aux | sleep 3", and psize.aux counts the 128-byte writes that complete, so it looks as though this runtime lets one more 128-byte write through than a single large write can use. I have not seen this build's pipesize.h, so that part is inference.
Isn't this a bug in MSYS2, maybe in how it simulates pipes? If the
pipesize is 65536, but it doesn't error until after it allows one
more write past that, how is that not a bug?
