Re: configure's __thread test

[Jonathan Bachrach <jrb@xxxxxxxxxx>]

if i recall correctly, we ended up not using thread local variables 
because they weren't available in gcc at the time, but stubbed them out 
for the future.  we could revisit them and perhaps get a faster 
implementation by using them for the language registers.  i'm not 
convinced it would improve over the current strategy though.

in the meanwhile, i should disable the configure scripts tests for 
thread local variables...
