You can also disable locking on a specific configuration.
This can be useful if a plugin configured locking on all configurations but you happen to add one that should not be locked.

// Goroutine preemption
//
// A goroutine can be preempted at any safe-point. Currently, there
// are a few categories of safe-points:
//
// 1. A blocked safe-point occurs for the duration that a goroutine is
//    descheduled, blocked on synchronization, or in a system call.
//
// 2. Synchronous safe-points occur when a running goroutine checks
//    for a preemption request.
