Filesys::POSIX::Mem::Bucket - Regular file I/O handle
Filesys::POSIX::Mem::Bucket provides an implementation of the interface in Filesys::POSIX::IO::Handle that allows access to the regular file data of a file in a Filesys::POSIX::Mem filesystem hierarchy.
Internally, the bucket can store up to a specified maximum number of bytes until said data is flushed to a temporary file on disk, backed by File::Temp.
