Subject: Re: Writing event hooks called from C extensions

On #ruby-lang, drbrain explained to me that I should run my event loop
handler inside a seperate thread.
I understand why that should be, but I've no clue how to launch a
seperate thread from a C extension and communicatie back to the Ruby
thread.
Can anybody give me a head start?
