In <4320@june.cs.washington.edu>, Kenneth Almquist indicates that the following actions are illegal (ETXTBUSY): 1) Opening a file that is being executed. 2) Executing an open file. 3) Deleting the last link to a file that is being executed. (1) and (2) are somewhat wrong. Only WRITE access is incompatible with execute access. (1) should be "opening a file for writing that is being executed", and (2) should be "executing a file that is open for write". Check the manual pages on this [try intro(2) and exec*(2)] (3) is handled invisibly by the kernel. The image stays around as long as it is being executed, then disappears. Andrew L.
