What should be achieved?

Context

While non-blocking I/O system calls such as poll and select work well with a few clients, what if we want to scale to thousands of clients? These calls start to behave like a bottle neck and may need a better approach like kqueue or epoll which use an event based approach rather than a single polling one.

What should be achieved?

"I, as a client, want the server to respond me in a reasonable amount of time in spite of active connections"

• Be able to handle thousands of multiple requests in a single thread
• Make this feature work for both Linux and macOS

I'm trying to add a feature to be able to build in different platforms. This make variable: https://github.com/42AGV/webserv/pull/21/files#r713369103 to be able to build this https://github.com/42AGV/webserv/pull/21/files#r713370998 differently depending on the platform (otherwise it keeps failing in either macOS or linux).
I've spent the last few days catching up with main's changes, but now I should be able to slowly start to merge some of these into main.
