Symptoms

Previous releases suffered from a race condition where the pool system would be partially initialized on one TMM, but HSL would attempt to use a pool handled by a TMM that hadn't finished initializing.

Impact

TMM cores in the high-speed logging code while starting up.

Conditions

This is a race condition.

Workaround

None.

Fix Information

Use a per-TMM flag instead of a global flag to indicate HSL readiness.
