Pedro Alves 2278c276a8 gdb.threads/manythreads.exp: clean up and add comment 
In git b57bacec, I said:

> was actually caught by the manythreads.exp test.  Without that bit, I
> was getting:

This commit factors out the two places in the test that are effected
by this, and adds there a destilled version of the comment above.
