Re: [swift-corelibs-dev] NSTask and NSFileHandle implementation

2016-04-19 Thread Daniel Eggert via swift-corelibs-dev 
Wouldn't it still be a huge win to use dispatch for reading from / writing to a

2016-04-19 Thread Daniel Eggert via swift-corelibs-dev 
I don't think it compiles, but I haven't tried, yet. I've been trying to keep 
it up-to-date with master.
