HTTP extension beta - finally, how to handle errors in libevent pool?

Hello. I have spent several hours trying to figure out how to handle exceptions caused by socket problems (timeouts for example) in curl/libevent pools. For example, say we have 200 simultaneous requests pushed into pool via Pool->attach() and executed via Pool->send(). If at least one of them fail due to timeout or whatever else, PECL_HTTP will throw an exception and stop executing all other 199 requests. How to work this out? I have tried to wrap Pool->send() call with try .. catch block and call Pool->send() after exception again, but it returns just immediately. Thanks in advance for help, Yuri Egorov.
