Richard Purdie 06c6db7929 bitbake/runqueue.py: Avoid starvation of events to the server

The server UI was reading 1024 bytes, then sleeping for 0.25 seconds. Since
most new LogRecord events are larger than this it leads to a build up of data
which is only processed slowly, leading to a bottleneck and a slow down of
all bitbake processes.

Thanks to Dongxiao Xu <dongxiao.xu@intel.com> for the great work in debugging
this. A large value has been left in for the read() command just to ensure some
fairness amongst process handling if a task tries to log truly huge amounts of
data to the server, or goes crazy and ensures the main loop doesn't stall.
