+# go-detect-race
+
+Check if the race detector is running.
+
+I didnt find a variable to check quickly enough so I made this.
+
+
+## Usage
+
+```go
+import (
+  detectrace "github.com/jbenet/go-detect-race"
+)
+
+func main() {
+  if detectrace.WithRace() {
+    // running with -race
+  } else {
+    // running without -race
+  }
+}
+```
+
+## Why?
+
+Because the race detector doesnt like massive stress tests. Example:
+https://groups.google.com/forum/#!topic/golang-nuts/XDPHUt2LE70
+
+## Why didn't you just use...
+
+Please tell me about a better way of doing this. It wasn't
+readily apparent to me, so I made this. But i would much prefer
+an env var or some already existing var from the stdlib :)
