After importing ESRI Shapefile, v.in.ogr leaves map with name MYMAP_tmp.
Imported vector is fine, it's possible to use g.remove to delete _tmp
file.

can we isolate what bit of code is creating that error message? For some
functions the mixed slashes seem to work ok, for others not. It would be
good to know exactly which unlink() etc is safe or not so we can do a bulk
audit, and I'm not a fan of 'fixing' stuff which isn't actually broken as
it just clutters the code.

It's not / vs \ issue. Here's output of current 6.5 on Vista.

I have full write access to that directory and also I can delete all files
with g.remove.
This leads to timing (or background process) issue - it's not possible to
delete open file in Windows. Now we need to figure out where closing file
handle takes more time than simply calling Vect_close.
Some notes: I disabled file indexing and my antivirus software to prevent
file locking by those activities - no changes. Also I see this error only
when importing small files (i.e. one with 77 points) and not large ones.
If we will not manage to find real cause of this issue, we can IFDEF small
sleep on Windows to guarantee release of all file handles before trying to
unlink coor et al.
