Process.{get_memory_info, get_ext_memory_info, get_memory_percent} leaks memory.

What steps will reproduce the problem?  
1. Repeatedly call Process.get_memory_info(), Process.get_ext_memory_info(), 
Process.get_memory_percent()
2. Observe explosive memory usage

for proc in psutil.process_iter():
    proc.get_memory_info() 

What is the expected output?  
Memory usage stays relatively flat 

What do you see instead?  
Consumes tons of memory 

What version of psutil are you using? What Python version?  
psutil 1.0.1
python 2.7.5 

On what operating system? Is it 32bit or 64bit version?  
Windows 7 SP1 32-bit 

Please provide any additional information below.  
Looks like the root issue is the call to 
_psutil_mswindows.get_process_memory_info (and probably 
_psutil_mswindows.get_process_memory_info_2)

You're right: I can reproduce the problem with 
_psutil_mswindows.get_process_memory_info_2().
This also means we currently does not have a test case for this.
More later.
