fnlock: Locking for function calls and queuing on lock

fnlock is a module that allows locking on asyncronous functions and queuing of function calls, to be called on release.

Installing

npm install fnlock

Using

Simple use:

var fnlock = require('fnlock');
function run(arg){
   fnlock.lock(function(release){
          console.log("Enter "+arg);
          setTimeout(release,1000);
       });
}
run(1);
run(2);
run(3);

It's supposed that the script takes 3 seconds to run.
