Upon further investigation, it turns out that it doesn't.  My bug
was caused by libc_delete_hook() clearing the newlib reentrancy
struct pointer before the code Fernando pointed out gets to run.

I don't know if this is how it's supposed to work and the manual
forgot to mention "don't call libc from a Thread_delete extension,
or if it's a bona fide bug.
