When to compile macros

[pcanal]

As as side note, this

@amarcine

for i in 1 2 3 4 ; do
  root -b -l -q 'macro.C+("'$i'")' >& log.$i.txt &
done

I would get crashes presumably because of the library being rewritten by 4 processes at the same time or maybe because ROOT was unable to decide if it needs to recompile or not.

can be fixed in v5 and v6 with something like:

root -b -l -q -e '.L macro.C+' >& log.compilation.txt
for i in 1 2 3 4 ; do
  root -b -l -q 'macro.C+("'$i'")' >& log.$i.txt &
done
