  I've wrapped Makoto Matsumoto and Takuji Nishimura's code in a namespace
  so it's better encapsulated. Now you can have multiple random number generators
  and they won't stomp all over eachother's state.
  
  If you want to use this as a substitute for Math.random(), use the random()
  method like so:
  
  var m = new MersenneTwister();

Orien is correct, it is the fork() system call triggered by ProcessBuilder or Runtime.exec or other means of the JVM executing an external process (e.g. another JVM running ant, a git command, etc.).

There have been some posts on the Jenkins mailing lists about this: Cannot run program "git" ... error=12, Cannot allocate memory

There is a nice description of the issue on the SCons dev list: fork()+exec() vs posix_spawn()

There is a long standing JVM bug report with solutions: Use posix_spawn, not fork, on S10 to avoid swap exhaustion. But I'm not sure if this actually made it into JDK7 as the comments suggest was the plan.

In summary, on Unix-like systems, when one process (e.g. the JVM) needs to launch another process (e.g. git) a system call is made to

* PHP Regex to validate a Twitter hashtag
* 
* Useful for validating a text input (an HTML form in your CMS or custom application) that must be a valid Twitter hashtag.
* Valid examples: #a, #_, #_1, #_a, #1a, #áéìôü, #123hàsh_täg446
* Invalid examples: #1, ##hashtag, #hash-tag, #hash.tag, #hash tag, #hashtag!, (any hashtag that is more than 140 characters long, hash symbol included)
* 
* Regex explanation:
* First, the lookahead assertion (?=.{2,140}$) checks the minimum and max length, as explained here http://stackoverflow.com/a/4223213/1441613
