+The race detector currently allocates an extra 8 bytes per defer
+and recover
statement. Those extra allocations are not recovered until the goroutine
+exits. This means that if you have a long-running goroutine that is
+periodically issuing defer
and recover
calls,
+the program memory usage may grow without bound. These memory allocations
+will not show up in the output of runtime.ReadMemStats
or
+runtime/pprof
.
