Functions that are unsafe to be used from event callbacks?

[Joerg Pommnitz <pommnitz@xxxxxxxxx>]

Hello all,it seems that there is a number of functions that are unsafe to use inside callbacks from  ssh_event_dopoll. Are these functions documented somewhere? I found out the hard way that anything that calls ssh_channel_close will block the event loop and calling ssh_event_remove_fd from a callback causes use after free errors.
