It does this primarily to get async I/O without using an async frameworks.
As typically applied, it replaces threads with greenlets, making what was a
multi-threaded application single-threaded.

I am, although multithreadedness isn't very relevant, aside from the fact
that asynchronous frameworks are often used to avoid use of many threads.

Asynchronous APIs are extremely invasive.  They violate separation of
concerns because once a function is asynchronous, pretty much everything
above it in the call stack has to be asynchronous too.  IMO, they also
invite fails because people will tend to use them, because fashion, without
understanding the ramifications of blocking, especially by non-I/O code.
