comments on proposed uthread_write.c changes

[Dan Langille]

A problem with pthreads and EOT has been identified.  See PR 56274.  It
was suggested the solution was probably just a matter of changing one of
the >0 tests to >=0 in uthread_write.c

Any comments on that?

Here's a diff I came up with after looking at
src/lib/libc_r/uthreaduthread_write.c.  Any suggestions/comments?

I plan to apply and test this later in the week.
