I did 'apt-get dist-upgrade'.  The following packages were upgraded and
the mem/tlsf_malloc.c warnings went away:

apt apt-utils base-files gnupg gpgv libapt-inst1.5 libapt-pkg4.12
libc-bin libc-dev-bin libc6 libc6-dev libcurl3 libcurl4-openssl-dev
libgcrypt20 libglib2.0-0 libglib2.0-bin libglib2.0-dev libgssapi-krb5-2
libhogweed2 libk5crypto3 libkrb5-3 libkrb5support0 libmysqlclient-dev
libmysqlclient18 libnettle4 libpam-modules libpam-modules-bin libpam0g
libpcre3 libpcre3-dev libpcrecpp0 libssh2-1 libssl-dev libssl1.0.0
libsystemd0 libtiff5 libtiff5-dev libtiffxx5 libudev1 linux-libc-dev
multiarch-support mysql-common openssl perl perl-base perl-modules
systemd systemd-sysv tzdata udev

Sorry about the noise.  Now the once below (plus tls module ones)
remain.  They appeared already before 4.4.
