[9fans] Alt structs declared static in acme's threads

[david jeannot]

Hi,

Is there a reason why some Alt structures in
acme and rio's threads are declared static?

/sys/src/cmd/acme/acme.c:363:   static Alt alts[NKALT+1];
/sys/src/cmd/acme/acme.c:428:   static Alt alts[NMALT+1];
/sys/src/cmd/acme/acme.c:719:   static Alt alts[N+1];

Thanks, david.
