Use a maximum of 3/4 of the space in the temporary directory, to avoid the "quota exceeded" errors on /dev/shm seen on some OSes during testing.

Add timed signal interruption to the read side as well as the write, so that a non-write transfer method like splice or copy_file_range will still get interrupted if it takes too long.

Cap the amount passed to splice() and copy_file_range() to a specific value, don't just pass SIZE_MAX, since that value can cause errors, making the transfer fall back to read()/write().
