throwTo & block statements fixed in GHC 6.6.1

The problem which used to be described here has been fixed in GHC HEAD and this will be included in GHC version 6.6.1

I have built (Feb 9, 2007) the HEAD version of GHC and this problem is no longer present.

See the ticket at [1] and the comments near the top of [2].

The description which was here has been deleted, but is still available in the historical views of this page.
