AsyncBufferedReader misses messages

Hello,

I'm using can.AsyncBufferedReader(), and it seems if there is too much time time between reader.get_message() calls then messages are lost. They are still seen by wireshark, but not from reader.get_message(). Is this the expected behavior? Is there anything that can be done about this?

Even very small sleeps like time.sleep(0.001) will cause this issue.

OS and version: Ubuntu
Kernel: 5.4.0-107-generic
Python version: 3.8.10
python-can version: 4.0.0
python-can interface/s (if applicable): socketcan w/ peak_usb

Any help would be appreciated.
