Requested explanation of why this is desirable. |

An elaboration of the pros and cons of Pth over LinuxThreads will follow later. I guess there will be no clear preferred choice. In this case, it would be nice if it was possible to choose the threading library used at configure time (e.g. configure --with(out)-pth to force/disable Pth use). |

For the current shortcomings of GNU Pth with Python also cf. my Bug report #383 and Oli Andrich's #296. LinuxThreads are a kernel-space implementation of POSIX threads. GNU Pth is a user-space implementation. As a user-space implementation, it tends to offer better performance (less penalty for threads-switching) and portability, but can't provide real concurrency. That's why the test_thread (cf. #383) runs really slow, and that's also why the readline problem (cf. my bug report #196) goes away with Pth threads. For the sake of concurrency, I'd clearly prefer LinuxThreads. Pth should be a fallback if nothing else is available I guess. Having said that, I still would prefer if Pth were a configure-time option --use-pth so that I could override any other threading system. |

I've applied this patch (basically). I moved the Pth check even further down. |
