 Yes, there are a lot of repeated calls like this
 
    2505   2505 emacs    CALL timerfd_settime(5,1,0x7f7fff7b11a0,0)
    2505   2505 emacs    RET   timerfd_settime 0
    2505   2505 emacs    CALL  __sigprocmask14(3,0x7f7fff7b11f0,0)
    2505   2505 emacs    RET   __sigprocmask14 0
    2505   2505 emacs    CALL 
 __sigprocmask14(1,0x7f7fff7b1200,0x7f7fff7b11f0)
    2505   2505 emacs    RET   __sigprocmask14 0
    2505   2505 emacs    CALL  __clock_gettime50(0,0x7f7fff7b11b0)
    2505   2505 emacs    RET   __clock_gettime50 0
    2505   2505 emacs    CALL __timer_settime50(4,1,0x7f7fff7b11a0,0)
    2505   2505 emacs    RET   __timer_settime50 0
 
 
 sigprocmask is called when not reproducing the bug too. The others, the 
 timer and clock functions are called only when clicking on the menu bar.
