It's another ugly hack, but I think you could use a string eval. Create the string dynamically, including locks to the variables you need and including the work to be done and the signalling, then eval the string. I'm not sure that's worth it just to avoid a goto call. (You may have just discovered a good use of goto.)

I had to figure out something similar in Object::LocalVars, except I needed to localize a bunch of things instead of locking them. In that case, though, the list of variables is known at compile time, so the eval installs a localizing subroutine only once and efficiency of string eval isn't an issue.
