os_dump_core() uses abort() to terminate UML in case of an
fatal error.
glibc's abort() calls raise(SIGABRT) which makes use of tgkill().
tgkill() has no effect within UML's kernel threads because they
are not pthreads. As fallback abort() executes an invalid instruction
to terminate the process. T
