An embodiment of the invention pertains to a method that includes an operating system, program components running on the operating system, and a file system associated with one or more files. Responsive to a write request sent from a specified program component to the operating system, in order to write specified data content to a given file, the method determines whether the write request meets a criterion, which is derived from the identity of at least one of the specified program component, and the given file. If the criterion is met, a message is immediately sent to release the specified program component from a wait state. Data portions of the specified data content are then selectively written to a storage buffer, and subsequently written from the buffer to the given file.
