Finally figured this out, its not in the manual (maybe for the best...)
-----------
julia> f = open("std.log","w")
IOStream(<file std.log>)
julia> p=spawn(`julia -e 'println("f");error("g")'`, Base.DevNull, f, f)
Process(`julia -e 'println("f");error("g")'`, ProcessRunning)
julia> close(f)
shell> cat std.log
f
ERROR: g
in error at error.jl:21
