Subject: Avoid test failures on Hurd
X-Git-Tag: archive/raspbian/0.25.3+dfsg2-5+rpi1^2~4
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=7ab36c39a456446ffe59127a2a9183e3c9bae44b;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)
