    virNetClientSetTLSSession: Restore original signal mask
    
    Currently, we use pthread_sigmask(SIG_BLOCK, ...) prior to calling
    poll(). This is okay, as we don't want poll() to be interrupted.
    However, then - immediately as we fall out from the poll() - we try to
    restore the original sigmask - again using SIG_BLOCK. But as the man
    page says, SIG_BLOCK adds signals to the signal mask:
    
    SIG_BLOCK
          The set of blocked signals is the union of the current set and the set argument.
    
    Therefore, when restoring the original mask, we need to completely
    overwrite the one we set earlier and hence we should be using:
    
    SIG_SETMASK
          The set of blocked signals is set to the argument set.
