PS3:

aside from fixeria's comments: I'd appreciate some kind of illustration why 20 was chosen. […]

First of all, this is not alone the ultimae fix/improvmement for this code, see it as a quick improvement fixed the problem spotted in SYS#5922 where basically we saw that osmo-bsc schedules paging at a rate of 2 sec (due to scheduling 1 pag_req every 0.5 secs).

Since in there we saw figures of ~210 req/m = ~3.5 req/s, that meant we need a rate >=4 req/s.

Since I also saw 20 to be the amount of slots provided by the credit timer, I also though sending 20 at once was acceptable. I didn't do a big analysis and I could go for a smaller number, like 10. But as I said in the end I expect this to be a quick & temporary improvement step.
