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 lock with function call queuing:

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.

Setting lock state on a function

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

fnlock.lock('run');
run('YEY');
setTimeout(function(){ fnlock.unlock('run'); },1000);

It's supposed that the script takes 1 second to run.
