When __SINGLE_THREAD__ is defined, stdin, stdout and stderr needs to
have their _lock instance initialized. The __sfp() method is not
invoked for the 3 mentioned fds thus, the std() method needs to handle
the initialization of the lock.

This is more or less a revert of 382550072b49430f8c69adee937a0ba07bd385e6

Hello Jeff,

The description should have included a "not". Sorry about that.

Kind regards,
Torbjörn

Hi Torbjorn,

Could you clarify?  Your description and title says when SINGLE_THREAD, but
your patch is #ifndef __SINGLE_THREAD__.

Could you clarify?  Your description and title says when SINGLE_THREAD, but
your patch is #ifndef __SINGLE_THREAD__.
