Closing files opened with Open3.popen

Is there anyway to close a file that I opened with Open3.popen ? I’m
running a lot of external process (and capturing their stderr), but if
the process runs too long eventually I get a "Too many open files"
error.

~ > ruby -r open3 -e ‘ios = Open3::popen3 “sh”; system “ps”; ios.map{|io| io.close}; system “ps”’

Use IO#close.
