rolling heap doesn't deal with multipage allocations

trying to register 256 file descriptors with epoll:

zero (length=4096, x=0x1001a0000) at ../runtime/runtime.h:61
61 ((u8 *)x)[i] = 0;
(gdb) bt
#0 zero (length=4096, x=0x1001a0000) at ../runtime/runtime.h:61
#1 resize_table (buckets=512, z=0x1000580e3) at ../runtime/table.c:66
#2 table_set (z=0x1000580e3, c=c@entry=0x105, v=0x10019cc90) at ../runtime/table.c:120

rolling is dead? we can probably let this one die?

Ok, I'll remove it in my active PR. We can always dig it up should we need something like it in the future but, yes, it's not being used at the moment.
