// 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.
//
// 3. Asynchronous safe-points occur at any instruction in user code
