[swift-corelibs-dev] Recommended posix_spawnattr_t for NSTask's implementation

[Dan Stenmark]

I hope to take a crack at implementing some of NSTask this weekend.  What are the recommended posix_spawnattr_t flags that should be set?  Do we also want to take the opportunity to expose the ability to override some of these flags (like POSIX_SPAWN_SETPGROUP) or do we want to avoid tying this with posix_spawn() too closely?
