%description
mimalloc (pronounced "me-malloc") is a general purpose allocator with
excellent performance characteristics. Initially developed by Daan
Leijen for the run-time systems of the Koka and Lean languages.
Notable aspects of the design include:
- small and consistent
- free list sharding
- free list multi-sharding
- eager page reset: when a "page" becomes empty (with increased chance
  due to free list sharding) the memory is marked to the OS as unused
  ("reset" or "purged") reducing (real) memory pressure and
  fragmentation, especially in long running programs.
- secure: mimalloc can be built in secure mode
- first-class heaps
- bounded
- fast

%description -l pl.UTF-8
mimalloc (wymawiane jak "me-malloc") to alokator pamięci ogólnego
przeznaczenia, o dobrej charakterystyce wydajności. Pierwotnie został
napisany przez Daana Leijena dla systemów uruchomieniowych języków
Koka i Lean. Główne aspekty projektu to:
- mały rozmiar i spójność
- rozdrobnienie list wolnego miejsca
- wielokrotne rozdrobnienie list wolnego miejsca
- oznaczanie wolnych stron jako nie używanych
- bezpieczeństwo (można zbudować w trybie zorientowanym na
  bezpieczeństwo)
- sterty pierwszego poziomu
- ograniczenie najgorszych przypadków
- szybkość
