| | | | | | | | | | | POSIX mmap(3) manpage stipulates mmap bumps the reference count of the file description. Thus keeping a file descriptor to maintain the reference is not necessary. If this didn't work, every extension .so would require a permanent FD, which is obviously not the case. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63908 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
