Thank you for testing this.

I tried these tests on a Fedora system I have access to, and reproduced 
these failures.

My theory is that it is because there are characters being used in those 
tests that have special meanings to the terminal, e.g. C-u for kill 
line. I suspect that due to changes in timing, these bytes are being 
sent to the Info program before the special meanings of these bytes are 
turned off.

I found a bug in the 'pseudotty' program used in the Info tests that 
meant that the code there to turn off the special interpretation might 
not work. After this, all the tests passed.

I will look at the logs you've posted to see if there is anything else.
