Hi,

we call from our haskell application the metis prover via

System.Process.readProcessWithExitCode "metis" filename ""

However, we are not able to get rid of this process if metis does not terminate by itself. In particular, wrapping this call into a System.Timeout.timeout does not work.

timeout works so far as it is possible to start another action, but the continuing metis process still blocks the whole system.

C.

Any suggestions how we should handle this ideally portably but first of all under unix. (ghc-6.12.3)

Take a look at the timeout program in GHC's test suite: http://darcs.haskell.org/testsuite/timeout/timeout.hs Cheers, Simon
