[Mono-dev] Build Broken?

[Greg Young]

I am running into this on a build ubuntu 14.14 box bootstrapped with
3.12.1 (first pull down of sources)

MCS     [net_4_5] mono-symbolicate.exe
MDOC    [net_4_5] cs-errors.tree
Error destroying handle 0x40d mutex due to 16

Stacktrace:

  at System.Threading.InternalThread.Finalize () <0x0001b>
  at (wrapper runtime-invoke)
