BUG/MEDIUM: threads: handle signal queue only in thread 0

Signals were handled in all threads which caused some signals to be lost
from time to time. To avoid complicated lock system (threads+signals),
we prefer handling the signals in one thread avoiding concurrent access.

The side effect of this bug was that some process were not leaving from
time to time during a reload.

This patch must be backported in 1.8.
