sthibault: do you think this could be related to https://github.com/linux-speakup/espeakup/pull/48 ?
(the reason for my guess: it is the only recent change within the espeak_thread function - and a buffer-full / wait condition feels like something that could occur semi-repeatably and could have edge cases) Although the change from that pull request is not included in the vanilla tarball of espeakup version 0.90 on GitHub, it is patched[1] into Debian.
