+Description of problem:
+Test hangs (about once every two executions) because the console emits an error and expected content is not found.  Console content on a failed test execution:

+Instead of the last 4 lines seen here, a successful test contains:
+
+```
+20:59:53 DEBUG| Sash command shell (version 1.1.1)

+20:59:53 DEBUG| <<< {'return': {}}
+```
+
+It was also observed that the test is much more prone to fail when it runs restricted to a single CPU (with taskset).  It's not clear to me if this is a Kernel or QEMU issue.
+Steps to reproduce:
+1. ./configure --target-list=rx-softmmu
+2. meson compile
+3. make check-venv
+4. ./tests/venv/bin/avocado run tests/acceptance/machine_rx_gdbsim.py:RxGdbSimMachine.test_linux_sash
