If this is true, than i would expect that slow routing table grow is caused
by Test-Quagga1 rate limitation on sending withdraws to Bird - when Bird
receives withdraw for some prefix from Test-Quagga1, it elects different
route for that prefix and announce that to Test-Quagga1.

It can be detected using statistics from 'show protocols all'
whether number of sent prefixes grows together with number of
received withdraws.
