Multiple issues detected by the thread sanitizer build
Description of problem:
Switching the tsan build in the CI from benchmark to check-unit revealed a bunch of issues even in our most basic tests.
Steps to reproduce:
1. configure --enable-tsan --cc=clang --cxx=clang++ --enable-trace-backends=ust --enable-fdt=system --disable-slirp
2. make check-unit
3. recoil in horror at the failures
