Problem with too much average load while running zabbix_server 1.4.4

Here is the patch:

I started getting high CPU usage messaged from our central Zabbix server node earlier this week. After I performed some other needed optimizations (Alternative PHP Cache and MySQL-innodb-heavy-4G.cnf) cpu load was was reduced but then I noticed zabbix_server processes exibiting the same behavior discussed in this thread. Recompiling my 1.4.4 Debian packages with this patch, has further reduced total CPU usages.

Previous load average: 1.78, 2.32, 4.40
Current load average: 0.48, 0.81, 1.08
