Latest volatility + malware.py (r93). Operating system is Windows 7 64-bit.

If it should take this long, this issue can be removed.

Unfortunately it does usually take that long. Apihooks is probably the most 
labor intensive plugin around. It has to disassemble code in every exported 
function of every dll of every process (plus then do checks of the iat, eat, 
syscall, etc). So despite saying that, I'm going to keep this issue open 
because I think some improvements can still be made...and will update the 
ticket here when possible.
