internal/trace: stress tests triggering suspected deadlock in tracer [1.23 backport]

[gopherbot]

@mknyszek requested issue #72740 to be considered for backport to the next 1.23 minor release.

@gopherbot Please open backport issues for Go 1.23 and Go 1.24.

When running with tracing enabled, this can cause a random deadlock with no workaround.
