In CouchDB's CI the small_pipeline test intermittently fails with
something like:

```
in function ibrowse_tests:'-small_pipeline/0-fun-5-'/1 (test/ibrowse_tests.erl, line 150)
  {line,150},
  {expression,"Counts"},
  {expected,"\n\n\n\n\n\n\n\n\n\n"},
  {value,"\n\n\n\n\n\n\n\n\t\n"}]}
```

Increasing the timeout a bit seems to help in local tests.
