Nope! :-(

Here's a test script.  For this bug.

-----
#!/usr/bin/cygtclsh80

set p1 [open |bash r+]

#NOTE: it doesn't matter if it is bash or sh

puts $p1 ls
flush $p1

gets $p1 lsline
puts $lsline
#end of script
-----

The bug is that the script will hang at the `gets $p1 lsline'.  It
should get the first line of the directory listing and print it one
the console.
