Subject: Ensure all backends _remember_ the connection has closed after
X-Git-Tag: r8855-g4f798d~2797
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=f8848be2d87086a2b0b75ea84c2e4a820aceb8f9;p=PuTTY_svn.git

Ensure all backends _remember_ the connection has closed after
receiving a network error. Should prevent the cascading-error-box
bug.
