HPC does not attempt to lock the `.tix` file, so multiple concurrently running binaries in the same directory will exhibit a race condition.
This sounds like something that shouldn't be too terribly hard to fix, once we determine exactly how we want to deal with contention. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13452 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
