No, I did not. Valgrinding with 2, 3, or 4 threads is OK. Any more

Hi folks,
It took me about 8 days to valgrind Sage on sage.math. In total, the
whole process generated about 3.1 GB worth of memcheck reports. And
the total number of reports is 2701. A mem leak hunter's paradise :-)

The #$ macro constructs a string input stream and eventually

Hm, since we wanted to get away from implicit functions, the consistent
think to do would be to always require the base when a user wants to use
the log function. I think that this could avoid some confusion. In every
CAS, I have to check in the documentation what the program means by
log(x).
