`core-fast/gets-async.cpp` (and possibly others) have blocking or completely non blocking read
On some systems the test core-fast/gets-async.cpp
and possibly others fail because they either block completely or don't block at all (and display an error) when the expected behavior seems to be a blocking call with a timeout.
TODO: Investigate cause of this, find other similar cases, fix.
