Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Denial of Service: An infinite loop can be triggered during clock uninstallation if the tick mode restoration in a finally block is not safely guarded, causing a persistent hang in execution.

Prototype Pollution: Directly calling '.hasOwnProperty()' on user-controlled or third-party-defined timer objects allows prototype pollution or overridden property definitions to crash or hijack check logic.
