[Texmacs-dev] texmacs trunk (svn rev 9712) using 100% cpu on Linux3.16kernel/qt4 , gprof and strace info

[Stephen Crowley]

Hi all, I'm running the latest texmacs trunk (1.99.2.something) and have
for some time been getting 1 cpu pegged out at 100% cpu. I've attached a
gprofile report.. is this a known issue? any ideas? It's annoying when
the cpu fan starts whirring unnecessarily, and also it wastes energy..

strace -f shows a these messages, looping quite quickly
