I noticed this a few months ago.  At the end of running the full gcc
testsuite there were over 60,000 handles in the expect.exe process, the
vast majority of which were these anonymous pipes that you show below.

I tried to reproduce it with a looping dummy "hello world" test harness
but couldn't.  I think it's something particular in the (quite
customized) gcc 'expect' harness.
