 The wp_tempnam() function is located in wp-admin/includes/file.php

 When you use download_url() to download a zip file from a url that has
 many GET parameters

 e.g. http://example.com/?arg1=val1&arg2=val2&arg3=val3 ...... argn=valn,

 wp_tmpnam() will generate a name for the temporary file from the list of
 args.

 e.g. arg1val1arg2val2arg3val3......argn=valn.tmp

 If this is long enough, on an Windows environment, it can weigh a lot to
 the limitation of maximum 256 chars for a path.

 When copying the contents of the zip file to the wp-content/upgrade folder
 for instance if the path of the WordPress install + the folder name + any
 path inside the zip file is longer then 256 chars an error will occur.
 "Could not create directory"

 Suggestion: allow the returned value of wp_tempnam() to be filtered. This
 will help with avoiding the long path issue with Windows
