-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512
So in the documentation:
UserspaceIOCPBuffers 0|1 If IOCP is enabled (see DisableIOCP above), setting this option to 1 will tell Tor to disable kernel-space TCP buffers, in order to avoid needless copy operations and try not to run out of non-paged RAM. This feature is experimental; don’t use it yet unless you’re eager to help tracking down bugs. (Default: 0)
Is this description still accurate, or is it better debugged nowadays? Would this be useful to set on machines with limited memory resources, e.g. the Raspberry Pi?
Thanks much for any insight.

Probably not -- it has no effect except on Windows.
