// This test attempts to verify proper placement of spawned remoteworkers
// by spawning them and then verifying that they were spawned in the expected
// process by way of nsIWorkerDebuggerManager enumeration.
//
// Unfortunately, there's no other way to introspect where a worker global was
// spawned at this time. (devtools just ends up enumerating all workers in all
// processes and we don't want to depend on devtools in this test).
//
// As a result, this test currently only tests situations where it's known that
// a remote worker will be spawned in the same process that is initiating its
// spawning.
//
// This should be enhanced in the future.
