Close race condition in ppoll test where SIGALRM was delivered before we actually reached ppoll This seems to be what triggered the intermittent failure in https://buildkite.com/julialang/rr/builds/1395#018aad32-437b-4d71-ac76-a211b2c5dc18
rr is a lightweight tool for recording, replaying and debugging execution of applications (trees of processes and threads). Debugging extends gdb with very efficient reverse-execution, which in combination with standard gdb/x86 features like hardware data watchpoints, makes debugging much more fun. More information about the project, including instructions on how to install, run, and build rr, is at https://rr-project.org. The best technical overview is currently the paper Engineering Record And Replay For Deployability: Extended Technical Report.
