hangs with recent cygwin versions

["Ben Wing" <ben at 666 dot com>]

i am using the latest 1.5.5-1, with everything updated via setup within the last
couple of days.  Windows 2000, all the latest sp's and patches.

ever since upgrading from 1.3.something to 1.5.5-1, i've gotten periodic hangs
of various sorts.  in all cases, the console is completely wedged and can only
be killed through the upper-right-hand close button.

[1] i have an expect script that runs telnet.  sometimes when run, it gets as
far as `Spawning telnet xxx ...' then wedges, with 100% CPU chewage.  this
appears to increase in frequency until eventually it happens always, and can
only be fixed by rebooting.
[2] for awhile i was getting 100% repeatable wedges [no CPU usage] by running
tail on a long file.  the following is what tail was attempting to display:

[in place of \x sequences are actual characters; none of these lines should
wrap, if they are, that's my mail reader's fault.]

it was hanging when trying to display the line with the weird characters in it.
last thing you'd see is the previous line.

unfortunately i can't reproduce this any longer.  instead, i get output like
this:

666:~/etc/users/wing/procmail 117$ tail procmail.log.old
  Folder: /usr/home/wing/users/wing/mail/Trash                             5211

where there's some text eaten but no hanging.
