An upload of google-perftools to yakkety-proposed has been rejected from
the upload queue for the following reason: "d/p/Use-initial-exec-tls-
for-libunwind-s-recursion-flag.patch wasn't really in the upload for
yakkety.".

Title:
  google-perftools can deadlock with dlopen on startup

Status in google-perftools package in Ubuntu:
  Fix Released
Status in google-perftools source package in Xenial:
  In Progress
Status in google-perftools source package in Yakkety:
  In Progress

Bug description:
  [Impact]
  Applications use tcmalloc and deadlock on startup (specifically impacting upstream testing of Ceph).

  [Test Case]
  Hard to reproduce reliably, so we'll perform a regression test with Ceph in Ubuntu and look for feedback from upstream on occurrance of this problem.

  [Regression Potential]
  Low; patch is already in use in CentOS and RHEL and has been accepted into upstream.

  [Original Bug Report]
  On the xenial version of libgoogle-perftools, tcmalloc can deadlock with dlopen on startup.  This was fixed upstream here:

   https://github.com/gperftools/gperftools/issues/786

  FWIW el7 also backported this fix to 2.4 to resolve this for us.

  The ceph bug tracking this issue is here:
