Re: [Gimp-developer] Is there any way to free Gimp memory and avoid restarting it?

it?  I have noticed this behavior of GIMP myself before, and also
thought this is not how it should be...

It’s the default behaviour for almost all programs. On Linux systems
you may be able to set M_TRIM_THRESHOLD_ to return memory to the
operating system in some circumstances, and also MALLOC_MMAP_THRESHOLD_
to make malloc() allocate memory in a way that gets reused more easily.
See the man page for mallopt.

On Unix systems (including Linux and Mac OS X) this behaviour is not
especially unfriendly: the unused space isn’t necessarily kept in main
