Bruce finally caught this bogon for me, Thank you Bruce !
Due to some part of the VM/buffer/pmap magic doing clustering, this bogon
managed to work better than 99.9% of the time. Amazing.
If You ever again see a weird message from the gzip code, please tell me.

2. Even if ttywait() fails, call ttyflush(FREAD) in ttywflush.
This two fixes guarantee that queues are empty after calling ttywflush()
