Hi,

Here is a small patch that adds the quite common "srfi-18" egg  [1]. It
adds  multithreading support for CHICKEN Scheme. Please consider it for
inclusion.

Thanks,
Kristian

The srfi-18 egg is a quite common dependency in the CHICKCEN ecosystem. Here
it is, along with its chicken-compile-file dependency.

in the second patch, and applied.

Thanks!
