experiences with forks and forks::shared?

Hi,

I was investigating threaded perl as an option for a server
architecture and came across the "forks" and "forks::shared"
modules which are drop-in replacements for "threads" and
"threads::shared".

This allows you to work with Perl's threading API even without
a Perl which is compiled for multi-threading.  It also gives
an option if you just prefer the characteristics of a multi-process
architecture over a multi-threaded architecture.

Does anyone have experience with these ("forks"/"forks::shared")?
Are they stable (i.e. "production-worthy" at VERSION 0.10)?
Anyone thought of using them with Apache/mod_perl to share data
between Apache child processes?
