Description
Describe the bug
Sometimes DebugProbes.install fails with the following:
Caused by: java.lang.IllegalStateException: The Byte Buddy agent is not installed or not accessible
at kotlinx.coroutines.repackaged.net.bytebuddy.dynamic.loading.ClassReloadingStrategy.fromInstalledAgent(ClassReloadingStrategy.java:171)

This occurs more frequently when running multiple tests in parallel1, so I suspect there's a race condition that is sensitive to load.
JDK version: Azul OpenJDK 11
kotlinx.coroutines version: 1.6.4 (originally reproduced on 1.6.2)
Kotlin release version: 1.6.21
Provide a Reproducer
So far I've only reproduced the issue in these large tests:
- https://github.com/world-federation-of-advertisers/cross-media-measurement/blob/8d0ffec21d8214116313f4c65d609bab84ad6f09/src/test/kotlin/org/wfanet/measurement/integration/deploy/gcloud/GCloudPostgresInProcessLifeOfAMeasurementIntegrationTest.kt
- https://github.com/world-federation-of-advertisers/cross-media-measurement/blob/8d0ffec21d8214116313f4c65d609bab84ad6f09/src/test/kotlin/org/wfanet/measurement/integration/deploy/gcloud/GCloudSpannerInProcessLifeOfAMeasurementIntegrationTest.kt
In these cases DebugProbes.install is called via CoroutinesTimeout.
