+ is quite simple, runs with 40kb stacks.
+ - You may tweak the logs to reduce the stack size further. When
+ logging something, we try to build the string to display in a
+ char array on the stack. The size of this array is constant (and
+ equal to XBT_LOG_BUFF_SIZE, defined in include/xbt/log/h). If the
+ string is too large to fit this buffer, we move to a dynamically
+ sized buffer. In which case, we have to traverse one time the log
+ event arguments to compute the size we need for the buffer,
+ malloc it, and traverse the argument list again to do the actual
+ job.\n
+ The idea here is to move XBT_LOG_BUFF_SIZE to 1, forcing the logs
+ to use a dynamic array each time. This allows us to lower further
+ the stack size at the price of some performance loss...\n
+ This allowed me to run the reduce the stack size to ... 4k. Ie,
+ on my 1Gb laptop, I can run more than 250,000 processes!
