Subject: sqlite3-ruby busy_handler example?

I'm having concurrency issues with sqlite3 and would like to implement a 
busy_handler as the reasonable busy_timeout value I've set isn't always 
sufficient.

I'm new to ruby and have tried creating both as a busy_handler method 
and class, searching mailing archives, Jamis Buck's blogs, and the net 
in general, but I'm apparently just missing it.  The API doc for 
sqlite3-ruby is at http://sqlite-ruby.rubyforge.org/sqlite3 - the method 
signature is
      busy_handler( data=nil ) {|data, retries| ...}
which confuses me right off the bat.

Can someone provide an example of a busy handler implementation and how 
it should/can be invoked?
