when t0 and t1 are spawned with t0's outputstream [1, 2] is piped into
t1's input, a new pipe is created which uses a copy of the t0's fd.
This leaves the original copy in Node parent, unattended. Net result is
that when t0 produces data, it gets bifurcated into both the copies
Detect the passed handle to be of 'wrap' type and close after the
native spawn invocation by which time piping would have been over.
