[R-sig-Geo] Closing readOGR handles

[Alexander Shenkin]

Hmm, I restarted R, and can't reproduce the issue.  I'll post back if
and when it happens again and I can narrow it down.

I'm on Win 7 Pro x64, running R 2.14.2 and RStudio 0.95.263.  I saw the
open filehandles by doing a search in Process Explorer.

thanks,
