julia> type Foo
proc::Base.Process
end
julia> a = Foo(spawn(`python -m SimpleHTTPServer`))
Foo(Process(`python -m SimpleHTTPServer`, ProcessRunning))
julia> finalizer(a, x->kill(x.proc))
julia> quit()
error in running finalizer: Base.AssertionError(msg="p.handle != C_NULL")
This only happens about half the time. When it does happen, the process is left as an orphan. When it doesn't, the kill executes correctly and kills the process.
I was able to replicate on the latest master (f9a6bbd) as well.
