[New-bugs-announce] [issue32138] android: test_faulthandler fails also on API 24

[Xavier de Gaye]

New submission from Xavier de Gaye <xdegaye at gmail.com>:

Issue 26934 skipped some tests of test_faulthandler on Android API < 24 to fix the problem that python does not crash upon _sigsegv(). But the same problem occurs on API 24 except randomly, you need to run test_faulthandler many times before reproducing it, see below few results in that case.

I propose to skip those tests whatever the value of the Android API level.
In that case the test.support.requires_android_level decorator is not used anymore and should be removed.
