Problem

Jun Liu reported on the Stackless mailing list, that calling PyTasklet_New( NULL, ...) crashes (http://www.stackless.com/pipermail/stackless/2017-April/006470.html). The documentation explicitly allows NULL as first argument.

Looking at the history of PyTasklet_New I found the changes 20dad21ded9c (2.7-slp) and dae0e80f141d (3.2-slp), which remove - probably by accident - a if (type == NULL) type = &PyTasklet_Type;. The documentation needs some love too: what does "via capture()" mean?

Proposed Solution

I'll re-add the check for NULL and update the documentation.
