lyx_mirror/src/frontends/qt4/GuiListings.cpp
Richard Heck fdbe775b9f This is the result of an audit of all static variables, looking
for possible thread conflicts, of the sort Georg resolved at
6a30211f. I have made static variables const where possible,
and marked cases that looked potentially problematic with the
comment:
	// FIXME THREAD
Many of these definitely are vulnerable to concurrent access, such
as the static variables declared at the start of output_latex.cpp.
Suppose, e.g., we were outputting latex and also displaying the
source of a different document.

I'd appreciate it if others could grep for "FIXME THREAD" and see
if some of these are harmless, or what.
