[SCIP] locking while separating

[James Cussens]

I have implemented a separator for a constraint handler I have written.
When profiling I find that most of the time is spent when my separator
calls my constraint hander's lock method:

                                 2             SCIPconsAddLocks <cycle 2>
[2184]
                             257328483             ChordalSeparate <cycle
2> [19]
[3]     49.2   27.00    0.64 257328485         consLockChordal <cycle 2> [3]
                0.35    0.00 110035069/224944534

                0.29    0.00 147293414/176070304

                                 498             SCIPaddVarLocks <cycle 2>
[2102]

I'm not sure why this is happening. Can anyone enlighten me?

Thanks,

James
