Cadence/ClearCase: improve speed of scan checkedout directories

See this idea on ideas.ibm.com

In one of our bigger projects we noticed that ClearCase Workarea Manager takes very long to complete the "scan checkedout directories" function. I took a deeper look and found that it executes
cleartool lsco -fmt '%n:%[object_kind]p\n' -cview -recurse
where this list in our case is a list of 42 paths, most of them in VOBs. It takes here approx. 5 min to complete - just to find there is no checkout at all!
On the other hand, using a different set of options, it is very quick:

$ gtime cleartool lsco -cview -avob -sh | & tee /tmp/out
0.05user 0.02system 0:01.15elapsed 7%CPU (0avgtext+0avgdata 52032maxresident)k
0inputs+0outputs (0major+3397minor)pagefaults 0swaps

Little more than a second! So I was wondering, whether the code couldn't be refactored such that it would work as follows:
- collect from all libraries defined in the context (those 42 in our case) the containing VOBs; in our case this is just a single one!
- set CLEARCASE_AVOBS= and run "cleartool lsco -fmt '%n:%[object_kind]p\n' -cview -avob"
- iterate over the output, filter for directories and match against the list of library directories
