agreed.

gcc 4.4.x generates slow and buggy code and well,

may be, I don't have any data to support this claim but if you do have
something it would be nice if you shared that here.

 let's not talk

gcc 4.5 has many fixes including the direct TLS register access through CP15
on armv7+ which should be some improvement for TLS access. May be its
worth to start trying it on armv7a and weed out any issues early in
its adoption.
and may be start using thumb2 if not done thus far for armv7+
