[TF2][Linux][x32] steamclient.so random freeze on shutdown

[bottiger1]

Linux x32 server now randomly freezes on server shutdown. Seems to be rare, happening maybe 1 out of 50 times.

This never happened before the last update.

Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
