Subject: Avoid test failures on Hurd
X-Git-Tag: archive/raspbian/1.5.3+dfsg-2+rpi1~1^2^2^2^2^2^2^2^2^2^2^2~9
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=414f65a604f18cb58358f21931dc48d7995c2b34;p=pandas.git

Avoid test failures on Hurd

Allow multiprocessing to be unavailable
Accept any errno not just 2 for (intentionally) nonexistent files
(Hurd appears to use 2**30+2)
