Hello Daniel,

the benefit of this approach is the isolation against the normal timer 
subsystem. Some task thats get executed of this implementation can need quite 
a lot of time, e.g. imagine restarting a hanged database process. Blocking 
e.g. the transaction timers for several seconds is not a good thing on a busy 
server.. :-)

A further benefit is the relative simple behaviour and implementation, this 
code is only app. 300 lines over all, this is much more easy for handling and 
debugging.

Cheers,

Henning
