Yes, works like a charm: Solaris 10/x86 results (both go and libgo) are
back to normal.  I'm only seeing two failures:

The 32-bit net/http test tails (may be transient):

--- FAIL: http_test.TestTransportPersistConnLeak (3.53 seconds)
:0: 	goroutine growth: 106 -> 181 -> 125 (delta: 19)
:0: 	too many new goroutines
FAIL: net/http

FAIL: runtime/pprof

Already reported as PR go/54873.
