By WWII, scientists had already begun looking at alternative gelling substances for routine use in bacteriology, but concluded that agar was still better as it is both firmer and easier to handle. Today, some specialized microbiology applications use the colloid carrageenan (extracted from red seaweed Chondrus crispus, or “Irish Moss”), a more transparent and less auto-fluorescent alternative to agar (agar emits its own background fluorescence when excited by light). However, for routine bacteriological use, carrageenan is more difficult to dissolve, requires higher concentrations, can degrade at high temperatures, and forms weaker gels, which may result in puncturing its surface during the plating of cells.
A note on forkingA practical detail that matters is the process that creates child sandboxes must itself be fork-safe. If you are running an async runtime, forking from a multithreaded process is inherently unsafe because child processes inherit locked mutexes and can corrupt state. The solution is a fork server pattern where you fork a single-threaded launcher process before starting the async runtime, then have the async runtime communicate with the launcher over a Unix socket. The launcher creates children, entirely avoiding the multithreaded fork problem.
