Maybe try removing the while-no-input wrapper from 
completion-preview--try-update temporarily, that should help avoid that 
effect, leading to easier debugging.

Overall, it sounds like completion is slow for you in those examples. 
Does pressing C-M-i after "gnus" incur the same (~1s) delay in eshell?
