I think that PR link is incorrect. Yes, I think we should consider dropping 32-bit official builds. Unless we can reduce the amount of mmap'd data.
One thing I noticed when running on a 32-bit machine a while back was that the mmap'd data is mapped multiple times for different OS threads. Setting GOMAXPROCS=1 helped, but only a little. There was some discussion about doing mmap on demand, but there was not enough interest in 32-bit to consider spending the time.
