There are two things involved here. The FILE objects and pointers to 
FILE objects. The stdio, etc. are pointers. These pointers are 
thread-local. The FILE objects are global and are used for the initial 
values of these thread-local pointers. If you want to get rid of the 
thread-local pointers, then you probably need a new configuration option.
