Contexts, scopes, mutexs and threading

[weepy]

Hi

Given multiple inbound requests, how is threading and scopes handled ?

E.g. I'm writing a server that validates input.

function myfunc(state, move) {
var x = 1

// various processing that will change x to another value.

return x
}

If there are multiple inbound requests, that call myfunc, are there
every more than one threads simultaneously within the function? If so,
in each thread is the variable x pointing to the same memory address
(in which case, the threads would interfere with each other). How
should one best avoid this ?

Bit confused here, so any help much appreciated.

No, never. Only one thing happens at a time.

Thanks Ryan, This answers a question Avi and I were discussing earlier this week!
