I would think that would depend on the process. How might one get the PIDs of all rm ed files that are still open? The OP did not specify what operating system he is using. When there are no more processes holding a deleted file open, the kernel will free up the inode and disk blocks. Processes do not have "handlers" by which they can be notified that an open, essentially locked file, have been removed from disk.
Johan, the lsof grep ' deleted ' works on Linux as well. I created somefile and opened it in VIM, then rm ed it in another bash process.

The file system may keep the blocks allocated to save time later especially if the file still remains open , especially when it was big enough before truncating.
At least that's what XFS seems to be doing. Thank you Peter. I am glad that you address the "why" in this post. Actually, if any process has the file open when this happens, deletion is postponed until all processes have closed the file. To create a symbolic link is Linux use the ln command with the -s option.
