Issue with #43: observe sync/wait in SQOPF test with ExaAdmm branch https://github.com/exanauts/ExaAdmm.jl/tree/bowen/qp

• testing with ] test, SQOPF stuck with sync/wait error as
  error.txt
• Running the following code block, SQOPF returns normally.

using SQP
using LinearAlgebra
using CUDA
