Time depends on how fast SRM can physically store your variabled in
non-volatile memory.

Hmmm. I never did that when developing that module. I'll try that.

SRM stores any variables without a newline. After all, there *are*
variables which (in theory) could sensefull hold an additional \n so I
decided on presenting the values as-is, with no newline at their end.

That should do.  Generally, I need to do some work on the module. During
2.5.x, it got modifies some times which broke it a bit (does still work,
but emits an error during operation and so on - that's not nice...).
