The problem is, that pth schedules threads in user space. To do this it just
schedules a new thread, whenever a running thread hangs on IO (or explicitly
yields). To get to know, when a program hangs on IO, you have to use special
IO routines from pth(like pth_write, pth_read, pth_select etc.). This means,
that multithreading does not work with GLib/pth, because Glib uses the
standard libc routines (write, read, select). As long as you don't use
multiple threads, everything is fine of course.

Bye,
Sebastian
