Bug#556887: libsasl2-modules-gssapi-heimdal: Heimdal GSSAPI module incorrectly built with mutexes

[Howard Chu]

The problem is slightly overstated; slapd won't deadlock. But its throughput
will be drastically degraded, as all SASL I/O will be completely serialized.
The server will perform as if it was single-threaded. In particular,
authentication requests will completely block all other activity until they
complete.
