SOAP calls using EventMachine

Is there any way to make non-blocking SOAP requests within EventMachine?

I'm creating a ruby application which interacts with the google adwords api (which is SOAP based), using the adwords4r gem. The application uses EM to receive messages over a stomp connection, and then processes those messages by making SOAP calls to the adwords api. Obv开发者_C百科iously I need those calls to be non-blocking, since the processing will be within the reactor thread. One option would be to use EM.defer, but I'd rather not have the overhead of a bunch of threads in a threadpool.

HandSoap can use EventMachine.

After earning a tumbleweed badge with this question I ended up asking on the #eventmachine IRC. Apparently there is no eventmachine-friendly options for making SOAP calls, besides using EM.defer
