We have not had the earth overrun with the locusts from the bottomless pit yet that are said to cause the men with the mark of the beast pain for 5 months - and they will seek death and not find it
 
Actually it says that they will cause all without the sealing to be tortured for 5 months.  It is an important distinction.  It could be that this will happen quite quickly after God seals the 144,000 or it could mean that God seals those who come to believe and that believers won't be tortured.  In many ways this is grace.  Though they seek death because they have a glimpse of hell, God doesn't let them die in unbelief...yet.
 
But on the whole I agree with your point.
