[New-bugs-announce] [issue25995] os.walk() consumes a lot of file descriptors

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Since 3.5 os.walk() consumes a lot of file descriptors. Its number equals to the deep of directories tree. Since the number of file descriptors is limited, this can cause problems.

This was the main reason for rejecting fwalk-based implementation of os.walk() (issue15200).
