comment Dump process core without killing the process
At some point gcore was a stand-alone program but I don't think it's part of the gdb package anymore - however you can run gdb --pid=<PID> and then use it's gcore command to dump a core file. gcore.c is a fairly simple program that is easily googlable if you want something lighter weight.

comment Best way to swap filenames
Something you should be aware of and fear - any program that has an open file handle to either one of those files will retain the open file handle after the rename because it's pointing to the same inode that it had when it originally opened the file. Until all programs that have the files open close them, this will be the case and cause data corruption if you expect that renaming them 'breaks' any existing writer handles.

Useful to know - and will probably be a future research item to look at - I'd still be concerned about an application filling up my ram by proxy of tmpfs/ramfs in /tmp. That gives me the heebie jeebies!

comment Is swap an anachronism?
Also interesting: solarisinternals.com/si/reading/tmpfs.pdf - The amount of free space available to tmpfs depends on the amount of unallocated swap space in the system. The size of a tmpfs file system grows to accommodate the files written to it, but there are some inherent tradeoffs for heavy users of tmpfs. Tmpfs shares resources with the data and stack segments of executing programs. The execution of very large programs can be affected if tmpfs file systems are close to their maximum allowable size. Tmpfs is free to allocate all but 4MB of the system’s swap space.
