gochan's test failure

Metadata

Description

I noticed a failure in gochan's tests today: http://salmonella-linux-x86.call-cc.org/master-debugbuild/gcc/linux/x86/2017/11/26/salmonella-report/test/gochan.html

 -- testing timers: each gochan-tick gets consumed by only one recv -----------
 10ms messages for 105ms means 10 messages ............................ [ FAIL]
     expected 10 but got 12
     (length results)
 hopefully different senders: (1 1 1 1 1 2 3 3 4 4 4 4)
 1 test completed in 0.124 seconds.
 1 failure (100%).
 0 out of 1 (0%) tests passed.
 -- done testing timers: each gochan-tick gets consumed by only one recv ------

I've never seen this one before. I'm reporting in case it can help to spot a difficult to reproduce issue.
