Excuse my ignorance, but why that? Are you saying we read item by item and
return to the event loop?!

That would definitely explain a speed problem..........

Simple optimization: read several items in one cycle, with a maximum of for
example 100 (=> probably almost a 50x times faster)

Better optimization: Measure the time you spend reading from the pipe. After
1/10 second (which could mean 10, 20, or 1000 items depending on the machine
speed), go back to the event loop. This guarantees a snappy user interface and
high speed when receiving the data.
