Comment (by tibbe):

 Implementing igloo's suggestion will solve my current problem. I'm still
 interested in workarounds that would allow me (by jumping through some
 hoops) to export the same API but internally daemonize the process using
 some C code. Note that I need to executed some Haskell code (that is
 single threaded) before I can invoke the C code.
