Known Haggis bugs and problems

• Highlighting of selected text in TextField is (visually) broken. You can select text, but the markup is not properly done.
• The scheduler in ghc-0.26 does not handle the case where only processes blocked for I/O and timeout are in the run queue. Fixed in the next release of GHC.
• A bug in the way the GHC 0.26 RTS handles blocked threads causes intermittent bus errors for Haggis programs that runs with well filled (>50%) heaps. Fixed in the next release of GHC.
• Haggis code will in some cases interact badly with code that uses the Haskell 1.3 I/O prelude/libraries in ghc-0.26, since the I/O code in 0.26 is not multi-threaded. Fixed in the next GHC release(?)
