Re: [9fans] Plan 9 Go 386

[Jeremy Jackins <jeremyjackins@gmail.com>]

I consistently fail at html/template. At one point I was hanging
indefinitely on some other tests (net/http I think) due to goroutines
never giving up control, setting GOMAXPROCS=2 fixed it. I'm not sure
if that's still an issue though.

I have a 386 which is capable of SSE2, and I'm up to date with sources.
