Hi,

I've committed the attached patch which restores the original flags in 
stdioConsole::read. The existing code was turning off O_NONBLOCK 
regardless of whether it was previously off.

FWIW, I found this while investigating a problem on my RHL8.0 system in 
which this function blocks when sid is running in the background. This 
patch is just something I noticed while looking. It does not solve the 
problem.

Dave
