Avoiding dropout in a time-consuming on_endofplayback()/on_endoftrack() function

Dear community!
Currently I'm trying to improve the great foo_vst component by adding proper latency support. I'm listening to a lot of vinyl with iZotopes RX declicker plugin in the chain. This plugin has a latency of about 3 seconds, is quite CPU consuming, and is reporting it's latency correctly via the vst interface. The idea is to process the last 3 seconds on a plsylist in on_endofplayback() by processing the vst effect n times with the chunk-size used also in on_chunk() and using insert_chunk() in a loop.
I was hoping that insert_chunk() works asynchronoulsy, i.e. every chunk delivered by insert_chunk() is immedialetly ready for playback. But it seems that all chunks inserted are ready only after leaving on_endofplayback(). So this might be the reason for the short dropout.

So is there a possibility to make inserted chunks ready for playback immediately and still stay in on_endofplayback()?
Or maybe tell foobar that the plugin needs x more samples so that it continues calling on_chunk() for additional x samples at the end of the playlist? Then I could even easily process vst tails correctly.

Thank you for any helpful comments in advance.
