unsigned/64bit counters?

Hi,

I've come across select_loop counter wrap (currently it is an 'int' variable).

Shouldn't counters be at least unsigned?

Does anyone disagree with having 64 bit unsigned counters? The
drawbacks I see are:
1) 3rd party utility that parse cache manager information must support
64 bit unsigned values
2) and that snmp mibs should be changed accordingly.

Regards,
