Bug#1072669: systemd: after upgrades systemd to 256~rc3-7 /proc/sys/fs/nr_open becomes 1073741816

[Wregyek]

Package: systemd
Version: 256~rc3-7
Severity: normal

Dear Maintainer,

After systemd upgraded from 256~rc3-2 to 256~rc3-7, /proc/sys/fs/nr_open
changes from 1048576 (0x100000) to 1073741816 (0x3ffffff8), causing some
applications (e.g. Tor Browser) to spend a lot of time to iterate through the
max filedescriptors and close() them before exec(), like
https://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2020q1/013821.html .
