[issue21116] Failure to create multiprocessing shared arrays larger than 50% of memory size under linux

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Instead of the loop you can use writelines():

    f.writelines([b'\0' * bs] * (size // bs))

It would be nice to add a comment that estimate why os.ftruncate() or seek+write can't be used here. At least a link to this issue with short estimation.
