Ack from me, under the assumption that OsBlockSignals() and
OsRelaseSignals() stack[1].

CC'ing KiBi for the d-i ack (out of principle).

Thanks,

[1] With 2:1.1.16.4.1, we get:

"""
    OsBlockSignals();
    while (timers && (int) (timers->expires - now) <= 0)
      DoTimer(timers, now, &timers);
    OsReleaseSignals();
"""

Plus

"""
 DoTimer(OsTimerPtr timer, CARD32 now, volatile OsTimerPtr *prev)
 {
     CARD32 newTime;

     OsBlockSignals();
     [...]
     OsReleaseSignals();
 }
"""

This works only if the signal handling stacks.
