Summary: carrierroute: faster init

Initial Comment:
It would be nice to move the initialization of the cr tables (during startup) to a child process, so openser can start faster.
If I remember correctly, a similar approach was implemented a while ago for the usrloc module.

Hello Henning,

I'm loading 1M+ cr routes and this is taking 60s in 1.3/1.4.  I will try
to run some tests to see the improvement in this particular case.
Using a separate child process for loading the routes seems to be the
right thing to do here.

Regards,
Ovidiu Sas

Hi Ovidiu,

i did today some tests with 200K routes. I could reproduce the slow
initialization that you (and others) reported. On my machine (not really
high end, local mysql, some other load) the module needs around 19 seconds
to start.

One thing that helps in this regards are the F_MALLOC improvements i
commited in revision 4813. With this changes applied the load time drops to
ca. 1/4, around 4-5 seconds. So it seems that the problem is not in the
module code, but in the memory manager startup behaviour.

With even bigger rule sets the improvements is probably not that big, but
perhaps you can give it a try.

Henning
