always download with only one thread

[xienian87]

Hello,

I am using pySmartDL 1.3.4 on ubuntu 16.04. Even if I set thread = 5 explicitly, the tmp file only has .000.

Does this mean pySmartDL only use one thread to download file?

Whereas when I use it on windows, every file has multiple tmp files: .000, .001, .002, .003, .004.

Can somebody provide instruction on how to use multi-threading download on ubuntu?

Thanks very much!
