Hhm, the test case appears in the form I posted in the POSIX test
suite and I assume POSIX 2003.1 explicitly mentions this test.

I looked a bit through the arch specific signal handling but haven't
understood it really. There is already some special handling for
returning calls to a signal handler. It tests whether a syscall was
interrupted but I cannot find out what really happens. The POSIX test
makes me think that at least for some syscalls the syscall should be
aborted with EINTR.
