When functions are sometimes sync and sometimes async lead to hard to

I find that using a simple Stream.prototype.pipe from the file stream

Here is a slightly cleaned up version of the code with comments as to why
it's doing what it does. (the `this.result` code didn't affect the output
and was a distraction since it was polluting the global scope)
function addasync(no1, no2, callback) {
res = no1 + no2;
callback(false, res); //
Anand, it appears some fundamentals about closures, scope, and callbacks
are confusing you. Some tips that may help.
1. Always use `var` when creating a new local variable or it will be
declared global and clobber existing variables.
2. Your `result` argument is a function. Every time you call
It would be hard to preempt the thread since node is single threaded, but
you could wrap the event sources and measure how long a tick took to run.
Then if it took longer than a threshold you could log a warning or throw
an error. Sadly there is no node api for easy wrapping of the event
sources
Using the canWrite function from vfs-local, you can do it with a simple
stat. https://github.com/c9/vfs/blob/master/local/localfs.js#L19-23
function canWrite(owner, inGroup, mode) {
return owner (mode 00200) || // User is owner and owner can write.
inGroup (mode 00020) || // User

I will mention that most browsers send the port as part of the host header.
So if you're testing locally using a custom /etc/hosts on port 8080 (or
just using port 8080 on the production machine), you'll need to account for
that in the host routing.
