Threads counted as processes

[skogan]

The following is a patch of a problem where Zabbix agent counts threads as processes on systems running kernel 2.4 (RedHat EL3, for example). This happens because on these systems threads appear as directories under /proc (just like processes) the only difference being a leading "."

This bug is still there in 1.6! I guess for some people it's hard to imagine that anybody uses any other flavor of Linux besides Ubuntu :(
