Disposing of streams from within their callback?

A quick question. I use CFStreams in my server. When someone logs out, I dispose of the endpoints like this:

CFReadStreamSetClient(otEndpointPtr->readStream, 0, nil, nil);
CFReadStreamUnscheduleFromRunLoop(otEndpointPtr->readStream, gMainRunLoop, kCFRunLoopCommonModes);
CFReadStreamClose(otEndpointPtr->readStream);
CFRelease(otEndpointPtr->readStream);
otEndpointPtr->readStream = nil;

CFWriteStreamSetClient(otEndpointPtr->writeStream, 0, nil, nil);
CFWriteStreamUnscheduleFromRunLoop(otEndpointPtr->writeStream, gMainRunLoop, kCFRunLoopCommonModes);
CFWriteStreamClose(otEndpointPtr->writeStream);
CFRelease(otEndpointPtr->writeStream);
otEndpointPtr->writeStream = nil;

Is it safe to do that from within a callback to the read stream (kCFStreamEventHasBytesAvailable, kCFStreamEventErrorOccurred or kCFStreamEventEndEncountered)?
