Unfortunately, it does.

Basically, when you're using threads, you don't have to use
O_NONBLOCK.  Data availability at the beginning of the read call
(including read, sysread, recv) is checked by select(2) implicitly in
the thread scheduler, and fread(3) read as much data available at each
call.  Thus, even when reading thread is blocked, other threads should
keep moving.
