semrelease may unblock a goroutine, but the act of unblocking a goroutine may emit an event, which in turn may try to acquire trace.lock again. It's safe to release trace.lock in readTrace0 for this because all of the state (one variable) it uses under the lock will be recomputed when it reacquires the lock. There's also no other synchronization requirement to hold trace.lock. This is just a mistake.
