Socket is interface to kernel crypto API so it is just waiting for
output.

Anyway, we had few problems with benchmark code on fast machines but it
should be fixed in 1.6.4.

Not sure if Ubuntu have cryptsetup 1.6.4 somewhere but it is in Debian
testing already.

  If it's ptrace'd (IE, ltrace -p $PID or strace -p $PID) then it will
  resume.

  However, please note that I am using an Intel chip that has builtin
  AES instructions, this may be related to a firmware/hardware issue
  rather than a specific problem with the software package.
