There's also a webimpress/safe-writer package (which is used by ocramius/proxy-manager since v2.6). Maybe it's worth a look.

Yep, can be done with package. @mnapoli i can rework it with package, what do you prefer?

Thanks for the responses. I don't think it's worth using an extra package, I'd rather keep dependencies as light as possible (proxy-manager is an optional dependency).

What you did looks good, let's merge that!

Thank you!

Nice contribution. I also encountered a broken CompiledContainer a few times.

Regarding #728 (comment), I would say it is worth the extra package/dependency because:

1. this kind of functionality might introduce "strange" behavior, such as: Avoid writing to temporary dir? webimpress/safe-writer#2
2. both ocramius/proxy-manager and php-di/php-di are used a lot, so sharing the this dependency only makes it more reliable, right and tested all over the world in different setups.
3. the package itself does not have any additional dependencies: https://github.com/webimpress/safe-writer/blob/e185e55135c240dc5f490cae8ea3ae8051959db4/composer.json#L12-L14
4. and maybe most important: it is well-tested: https://github.com/webimpress/safe-writer/tree/master/test

Just my two cents ;)
