Yes, I saw. With all the uClibc mess (especially as we also support
external uClibc based toolchains) I really prefer to not add any more
patches if possible.

No, it only triggers in rare cases. Afaik the issue is about locking
between the lseek and read/write, so it should only be an issue if you
have an application doing pread/pwrite from multiple threads with the
same file descriptor.

git gc was apparently such a case.

Lets hope not.
