Description
I am trying to use rr debugger with apps that use async io calls (e.g., io_setup) and looks like it's not supported yet. mysql for example uses async io and I am not able to record it. Any plans on supporting these syscalls?

Research direction
The issue reports that rr cannot record applications using async I/O syscalls such as io_setup, with MySQL given as an example. Start by reproducing the recording failure with an application using these calls; done means rr can record and replay such workloads, with the supported syscall behavior verified.
