Lower ASLR entropy on CI runners so ThreadSanitizer can run - #238
Merged

Conversation
The Thread Sanitizer job aborts every TSan-instrumented test with "FATAL: ThreadSanitizer: encountered an incompatible memory layout but was unable to disable ASLR" because the ubuntu-latest runner kernel defaults to vm.mmap_rnd_bits=32. The industrial_ci container shares the host kernel, so lower the entropy on the host before running it. Signed-off-by: Michael Carroll <mjcarroll.oss@gmail.com>

The Thread Sanitizer CI job currently fails on every PR, before any test code runs:
The
ubuntu-latestrunner kernel defaults tovm.mmap_rnd_bits=32, which is incompatible with TSan's memory layout. industrial_ci runs in a container that shares the host kernel, so this adds a step that lowers it to 28 on the host before industrial_ci runs.
