tty buffer/queue sizes should be larger
At present, we accept 256 bytes of input in cooked mode, and 512 in raw. 2K is a more usual amount.
I've hit these limits pretty regularly with automated processes, and a few times manually. The symptom of hitting the limit is usually your input being ignored, and a BEL being echoed back. For automated processes, especially, this is a real pain in the ass to diagnose.
