You were *very* lucky, because this code is absolutely full of mistakes
related to incomplete reads, inadequate or outright wrong error handling,
etc.
I was nearly done cleaning that up, when it sank into me that
fe-secure-gssapi.c uses static buffers for partially-read or
partially-encoded data. That means that any client trying to use
multiple GSSAPI-encrypted connections is very likely to see breakage
due to different connections trying to use the same buffers concurrently.
I wonder whether that doesn't explain the complaints mentioned upthread
from the Ruby folks.
(be-secure-gssapi.c is coded identically, but there it's OK since
any backend only has one client connection to deal with.)

This is gonna take longer than I thought.
