I guess the beginning of the written buffer is not page aligned, and the
system locks pages. Thus depending on the buffer alignment, the written
maximum can vary up to the size of one page.

Memory pressure? Git may consume large amount of virtual memory
during some operations, but I am not sure how it is translated in the
number of physical memory consumed by the process as well as what
quotas could be on that system. It would be interesting to see what
GetProcessMemoryInfo() returns when write() fails.
