And that's complete bullshit. The Open Group (aka "Unix") is pretty
damn clear. The request parameter is an "int", and OS X is buggy.

See for example

Ugh. I remember the pain we had with OS X when doing git too.
Performance problems, non-standard crap. Most of it was Mach being
slow, but the ioctl buggery seems to come from the FreeBSD roots..
