Describe the bug

The tests fail on Mac because p.profile("-d 2 -e itimer -i 1us --total -o collapsed") frequently runs longer than the 10-second timeout.

We observed the same effect on our internal test queue.

Expected vs. actual behavior

It should not time out, but it does. A sample for the runtime distribution on a M4 Pro MacBook:

Other runs observed runtimes up to 273 seconds.

Reproduction Steps

The following should produce failing tests regularly:

while true; do make JAVAC_TARGET=8 TESTS=test.cpu.CpuTests test; done

Additional Information/Context

The behaviour can be observed on

Async-profiler version

master-branch at the time of writing

Environment details

MacBook Pro M4, JDKs 21.0.6 and 23 (all versions)
