Hrm.  What is the FS segment standardly used for, if anything?

I'm familiar with Win32's use of it as a per-thread data area.  For 
example, "mov eax, fs:[0]" is a common instruction emitted by Win32 
compilers when setting up exception handlers.  This caused some problems 
with WINE when some (versions of) OSes would trash FS.
