   I'm betting it's NSURL resourceDataUsingCache: NO, which has a low-level memory leak.

   Test code, compile and let run, watch process mem usage gradually increase:

   Compile and run the following example code:

   int main (int argc, const char * argv[]) {
   	while( 1)
   	{
   		NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
   		NSString *prefsBBURL = @"http://planetx.geneseo.edu/bb/";
   		NSData *data;
   		NSURL *url;
   		// sorry about the pounding
   		url = [NSURL URLWithString: prefsBBURL];
   		data = [url resourceDataUsingCache: NO];
   		[pool release];
   	}
       return 0;
   }

   From what I've read and tested it could also be sheets that leak. I just posted so people know to check and perhaps re-launch Safari from time to time given the long uptimes many Macs see.

   Jake: That doesn't seem to leak on my system (running 10.5.1). It looks to me like Apple fixed it.

   In my experience Safari 3 leaks less than Safari 2. And it leaks less on Leopard than it did on Tiger. With Safari 2 on Tiger I had to restart Safari at least once a day, or it would be using well over a gigabyte of real memory.

   I think the Flash plugin leaks memory significantly, though.
