Revision 1.83, Thu Jan 25 23:22:32 2007 UTC (17 years, 4 months ago) by joris
Branch: MAIN
Changes since 1.82: +2 -2 lines
when acting as a server - immediatly after we checkout a file
remove its temp copy so our worklist doesnt contain a
bazillion entries when checking out src.
as a result, we now use very little memory in server mode.
found and tested by otto@
ok cool and the gang.
