Description Jan Kratochvil 2011-07-06 19:23:20 UTC 
gdb.python/py-evsignal.exp and gdb.python/py-evthreads.exp will have now KFAIL with gdbserver.

RuntimeError: Could not find event thread

I do not see anywhere target_find_new_threads call before Python tries to deal with the thread list.

    Remove is_remote kfail from gdb.python/py-evthreads.exp
    
    This testcase works fine with gdbserver nowadays.  So remove the
    kfail.

Comment 3 Tom Tromey 2022-06-05 15:01:32 UTC 
py-evsignal.exp still seems to fail with native-gdbserver.exp
and native-extended-gdbserver.exp (though they fail differently).
