Just a comment here: busy polling (on sockets, for timers, ...)
in user space never should be needed.

On Unix, the select() system call allows to wait for arbitrary file
descriptors to become ready, including sockets, and has a timeout to
allow for the implementation of timers. I am quite sure that Qt
internally uses this.
To wait on sockets in Qt (data to read available, error condition, ...)
with the standard event loop (thus, without polling), use QSocketNotifier.
And any "texmacs internal timers" should be based on QTimer.
