Hrm.  What about what Jeff already asked of the OP (and AFAICS never got
a reply)?

} If it's a race condition between the write and the subsequent read in
} the same process, then it would be solved by looking at the object
} later. Does "git cat-file -p 6838761d549cf76033d2e9faf5954e62839eb25d"
} work, or is the object forever inaccessible?

In your case: git cat-file -p 0b89efdeef245ed6a0a7eacc5c578629a141f856
