That's not quite right as I have to build binaries with --disable-sse (I build and distribute both with and without) so that some users on PII's don't get a sigill, even though the OS supports SSE. So it seems to unconditionally disable SSE sup...

Patch registers SIGTSTP hook where it sends reset terminal color control sequence using write and fsync. Handler is installed only if signal is not being ignored. Patch uses rl_free_line_state and rl_cleanup_after_signal to unhook readline from terminal, then it calls original TSTP handler using approach in URL below and again hooks readline using rl_reset_after_signal. Handling is based on code

Patch is here: https://github.com/openwrt/packages/commit/1263599f96f13f11d719ce336dfb6a639b32de98 . Probably needs to be modified for inclusion into mainline.

I've made two little patches to allow dovecot to be compiled on GNU/Hurd. Could you review them?

I am aware that there have been several posts related to ssh connections hanging, i have tried to read through most of them in the archives... I am posting this in hopes that it may present something new that will further help resolve this problem. The problem i am having appears to be similar to what others have reported where after typing exit in an interactive shell the connection is not
