>> * The 0MQ ABI exported by libzmq.so has been formalised; DSO symbol

>>
>> * OpenPGM has been updated to version 5.0.92. This version no longer
>>  depends on GLIB, and integration with 0MQ should be much improved.
>>
>> * zmq_poll() now honors timeouts precisely, and no longer returns if no

>>
>> * Blocking calls now return EINTR if interrupted by the delivery of a
>>  signal; this also means that language bindings which previously had
>>  problems with handling SIGINT/^C should now work correctly.
