Comment (by anonymous@…):

 I don't think the issue is QT, but rather the rather ancient level of
 glib2 supplied with Centos/RHEL. In the 2.22.5 version of gmain.c, the
 wakeup pipe is created blocking; in later versions the wakeup code is
 moved into a new gwakeup.c module and uses non-blocking pipes.

 A possible circumvention (haven't tried this yet) would be to modify QT
 src/corelib/kernel/qsocketnotifier.cpp to force registered file
 descriptors non-blocking.
