I made some small programs with functions to eat up some memory with 
giant sequences, and in every case 2.4 is faster than 2.3 in both 
filling up the memory (*many* times faster when building up a sequence 
with '&' or append) and returning from the function.  But the memory 
does not appear to be released (returned to system) as it does it my 
other program.  So benchmark programs show 2.4 faster than 2.3, but my 
"real" programs run slower, in the one case massively so (I just 
verified that again to make sure I wasn't crazy -- still takes 30 
seconds to exit function.)  Now I'm really confused...
