Panic on master with t.Parallel, go 1.9, and Reset

Reproducible test case:

> cat convey_test.go 
package convey

import (
    . "github.com/smartystreets/goconvey/convey"
    "testing"
)

func TestFoo(t *testing.T) {
    t.Parallel()
    Convey("Foo", t, func() {
        Reset(func() {})
    })
}

func TestBar(t *testing.T) {
    t.Parallel()
    Convey("Foo", t, func() {
        Reset(func() {})
    })
}

Output:

Using version 1.9.2:

> go version
go version go1.9.2 darwin/amd64

Using version 1.8.3, the test passes without issues

I have done a go get to get the latest master code, as well as cleared my pkg directory: still no fixes.
