Also, just checked via manually calling `stop()` as end-to-end tests after
building it.
```
df <- createDataFrame(list(list(1L, 1, "1", 0.1)), c("a", "b", "c", "d"))
collect(gapply(df, "a", function(key, x) { stop() }, schema(df)))
... 30 times
collect(gapply(df, "a", function(key, x) { x }, schema(df)))
```
The daemon does not die and the pipes were not left open at all in this
case.
