Resetting a timerfd empties the data on the fd, so if the timer is reset between triggering and us reading it, we may block trying to read it. Since we read events off a device in a loop, a device sending a continuous flow of events may cause the timer to trigger but delay reading it. If one of the events cause e.g. the tap timer to be set, the timerfd may be empty at the time of reading.

/*!@mainpage libinput ======== libinput is a library that handles input devices for display servers and other applications that need to directly deal with input devices. It provides device detection, device handling, input device event processing and abstraction so minimize the amount of custom input code the user of libinput need to provide the common set of functionality that users expect. Input event processing includes scaling touch coordinates, generating pointer events from touchpads, pointer acceleration, etc. libinput originates from weston, the Wayland reference compositor. The source code of libinput can be found at: http://cgit.freedesktop.org/wayland/libinput For more information, visit: http://www.freedesktop.org/wiki/Software/libinput/ Bugs can be filed in the libinput component of Wayland: https://bugs.freedesktop.org/enter_bug.cgi?product=Wayland&component=libinput Online API documentation: http://wayland.freedesktop.org/libinput/doc/latest/modules.html */
