Merge Cells don't works on many Cells - it's a bug (or a secret plan)?

Hi all!
Try to unite many cells in my output (around 100000, sometimes more) - to take this data to another program.
Mathematica (9.01) not unite it and immediately stops.
So, i print 10000 simple strings (for experiment), and try to unit them - again don’t work and stop.
10 strings may be united, but i need much more - may be, there are some ways to do this?

I used a Do with Print[j] inside and generated 13000 Print cells. They merged ok. Took a few minutes.
Shipping 10.0.0 on Mac 10.8.5 and Windows 7.
Is that a reasonable approximation to what you tried?

I am generating a notebook with 10^5 Print cells to try.

Mathematica 9.01, Acer TravelMate 360AWXMi - merge cells don’t work (on many cells).
But “Copy as a plain text” - works good, so, the problem was solved this way.
