I’m attempting to interrupt a `ccall` which is executed via `remote_call`:

`task = remotecall(call_solver, wid)`

where `call_solver` is a `ccall` and `wid` is 2, the current worker id being 1. I then try to interrupt it via `interrupt`, for example:

```julia
t = remotecall(call_solver, wid)
sleep(10)
interrupt(wid)

```

and the code doesn’t appear to actually stop executing. Is it possible to interrupt a `ccall`?
