The same here: when I start to add yum channels, smart is not able to finish    
its cache anymore.    
I checked what it was doing with strace -p, and there was a significant change    
after reaching 99%. It started to repeat these lines again and again, only with    
changing addresses:    
    
mmap2(NULL, 380928, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =    
0x4272a000    
munmap(0x42392000, 380928)              = 0    
mmap2(NULL, 380928, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =    
0x42392000    
munmap(0x4272a000, 380928)              = 0    
mmap2(NULL, 380928, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =    
0x4272a000    
munmap(0x42392000, 380928)              = 0    
mmap2(NULL, 380928, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =    
0x42392000    
munmap(0x4272a000, 380928)              = 0    
   
Before that there was sime kind of acitivty (I saw the channel names flying by,   
etc.). And it repeats to give out these lines for several minutes, so I do not   
think that's just because it takes so long to update the cache-system.  
Without the yum channels it takes only seconds to update the channels, even if 
the content of the channels is the same.
