Subject: [3.14] gh-154272: Skip more forkserver tests if the start method is unavailable ... 
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=9585cc32c6a3005f1e12169f553e8e2551ec6960;p=thirdparty%2FPython%2Fcpython.git

[3.14] gh-154272: Skip more forkserver tests if the start method is unavailable (GH-154499) (GH-154506)

Two tests were still not skipped: they were only guarded against Cygwin
and Windows.

(cherry picked from commit a2a846678e54b1b5defdccd451c573679094ff02)
