Whether or not Performer is affected is a function of the actions taken
in your signal handler. If you do something as innocuous as adding some
event to a queue (ensuring that access to this queue is protected from
signals) then you probably won't have a problem. If, however, you make
calls into Performer from within the signal handler, you will most
likely encounter problems.
