Comment(by wgmitchener):

 A bit more information:  I compiled Try2.hs with

 ghc -debug --make Try2.hs

 This is on Fedora 18 with ghc 7.4.1.  (FYI: I'm also using the development
 version of gtk2hs; darcs gives latest patch date of Tue Feb 19 16:39:46
 EST 2013).  Now Try2 fails with a concrete error message:

 Try2: internal error: ASSERTION FAILED: file rts/STM.c, line 1476

     (GHC version 7.4.1 for i386_unknown_linux)
     Please report this as a GHC bug:
 http://www.haskell.org/ghc/reportabug
 Aborted

 which seems maybe to have something to do with not doing one STM
 transaction inside another?  The function where that assertion happens is
 stmWait.
