Except that eventually you run the kernel out of resources.  We were
forced to confront that point very early when dealing with the SysV
API, because of the remarkably low resource limits it traditionally
has, but long-term resource leaks are never a good idea in any software.

Or are you designing this according to the widespread view that Windows
system uptimes are measured in small numbers of days anyway?
