pub const MAX_ABANDONED: usize = 4;Expand description
How many parses may be running past their deadline before another is refused outright.
Each one is a thread that cannot be stopped, so each one is a core this process will not get back. Four is enough that a person who opens a bad file, fixes it, and opens it again is never told no, and few enough that a four-core panel keeps a core to draw with.
Reaching it is Reason::NoThread, and it does not clear: the threads are
wedged for the life of the process, and the honest advice in that message is
to restart.
