In cc95bc2025 (t5562: replace /dev/zero with a pipe from generate_zero_bytes, 2019-02-09), we replaced usage of /dev/zero (which is not available on NonStop, apparently) by a Perl script snippet to generate NUL bytes. Sadly, it does not seem to work on NonStop, as t5562 reportedly hangs. Worse, this also hangs in the Ubuntu 16.04 agents of the CI builds on Azure Pipelines: for some reason, the Perl script snippet that is run via `generate_zero_bytes` in t5562's 'CONTENT_LENGTH overflow ssite_t' test case tries to write out an infinite amount of NUL bytes unless a broken pipe is encountered, that snippet never encounters the broken pipe, and keeps going until the build times out. Oddly enough, this does not reproduce on the Windows and macOS agents, nor in a local Ubuntu 18.04. This developer tried for a day to figure out the exact circumstances under which this hang happens, to no avail, the details remain a mystery. In the end, though, what counts is that this here change incidentally fixes that hang (maybe also on NonStop?). Even more positively, it gets rid of yet another unnecessary Perl invocation.
