Title:
  Archive::Zip does not close temporary  archive files

Status in libarchive-zip-perl package in Ubuntu:
  New

Bug description:
  Ubuntu 15.10 contains Archive::Zip v 1.49 that apparently has a bug
  that creating/updating a zip archive file does not close it , and
  creating many files generates "too many open files" error similar to
  this -

  IO error: Can't open <.......>: Too many open files at /usr/share/perl5/Archive/Zip/FileMember.pm line 40. Archive::Zip::FileMember::_openFile(Archive::Zip::ZipFileMember=HASH(0x23e62b0)) called at /usr/share/perl5/Archive/Zip/FileMember.pm line 30 Archive::Zip::FileMember::fh(Archive::Zip::ZipFileMember=HASH(0x23e62b0)) called at /usr/share/perl5/Archive/Zip/ZipFileMember.pm line 384 Archive::Zip::ZipFileMember::rewindData(Archive::Zip::ZipFileMember=HASH(0x23e62b0)) called at /usr/share/perl5/Archive/Zip/Member.pm line 1059 Archive::Zip::Member::_writeToFileHandle(Archive::Zip::ZipFileMember=HASH(0x23e62b0), IO::File=GLOB(0x24399d0), 1, 0) called at /usr/share/perl5/Archive/Zip/Archive.pm line 420 Archive::Zip::Archive::writeToFileHandle(Archive::Zip::Archive=HASH(0x242eda8), IO::File=GLOB(0x24399d0)) called at /usr/share/perl5/Archive/Zip/Archive.pm line 456 Archive::Zip::Archive::overwriteAs(Archive::Zip::Archive=HASH(0x242eda8), "<.......>") called at /usr/share/perl5/Archive/Zip/Archive.pm line 440
  Archive::Zip::Archive::overwrite(Archive::Zip::Archive=HASH(0x242eda8)) called at ./arcoper.pl line 57

  lsof -p <pid>    shows all /tmp/*zip files deleted, but still open, up to max open files  (1000  which is system default)
  Increasing number of files in limits.conf makes the problem generate less frequently.

  installing latest version 1.56  from cpan fixes the problem - Using
  many zip files correctly  closes them, does not generate errors, and
  lsof -p <pid> shows only several files (less than 20)
