-// This is the original ForkLock:

-// var ForkLock sync.RWMutex
-//
-// This requires importing sync, but importing sync causes an import loop:
-//
-// package tinygo.org/x/drivers/examples/net/tcpclient
-//        imports bytes
-//        imports io
-//        imports sync
-//        imports internal/task
-//        imports runtime/interrupt
-//        imports device/arm
-//        imports syscall
-//        imports sync: import cycle not allowed
-//
-// So for now, make our own stubbed-out ForkLock that doesn't use sync..
