/**
 * This function forcefully terminates the calling program if it is invoked inside a loader callout. Otherwise, it has no effect.
 *
 * @remarks This routine does not catch all potential deadlock cases; it is possible for a thread inside a loader callout
 * to acquire a lock while some thread outside a loader callout holds the same lock and makes a call into the loader.
 * In other words, there can be a lock order inversion between the loader lock and a client lock.
