Python and other garbage-collected systems gives the 
responibility for memory management to the runtime system instead
of the programmer. In this case the runtime system is designed
in a way that may cause problems in programs which is runing for a 
long period. For a highlevel/scripting language like python, 
it's certainly a benefit to remove the burden of memory management
from the programmer, even when the garbage collector in imperfect.

But of cause, this GC problem may prevent people from using python
for server software, until this problem is solved.
