'''WARNING''': there's currently a bug in the IPDL compiler that needs to be worked around (the bug should be fixed "soon"). If you use Shmem in a managed (i.e. not top-level) protocol, then the top-level protocol needs to use Shmem as well. You can work around this with the following hack | |||
protocol TopLevel { | |||
parent: Dummy(Shmem _); | |||
// etc. | |||
}; | }; | ||
