OK, I believe this.  the cygwin dll terminal emulation is fixed in the 6/10
release.

OK, I know this is still alpha or beta.  Obviously there are still bugs.
What I'm looking for is *relative* stability, not perfection.

If what you say is correct (and I'm hoping it is!), then I do have a "test
plan":  I simply throw away the broken version of cygwin1.dll and restore
the previous version.

OK, then it appears that every snapshot since 5/24 has this bug in it.  I'm
not exactly sure why it is showing up so frequently in my environment.  I
saw this virtually every time when piping
   ls | grep | perl

Could these two bugs be related?  It seems that when the terminal emulation
bug went away, simultaneously the fhandler_base::fork_fixup bug appeared.
