terminated modern session cause trouble for subsequent session #5730
Description
Please see code below. Short summary:
- a modern mode session is initiated, w. file download
- "Oh no, I don't have enough bandwidth for this" ->
^C - session is terminated, leaving waste in
.gmt/sessions/causing trouble for subsequent session.
Should there not be a trap for e.g. ^C which triggers cleanup?
$ ls -l .gmt/sessions/
total 0
#make plot - I want @earth_relief_10m
$ gmt grdimage @earth_relief_10m -JM15c -RNO -pdf map
